If a diameter of a circular chapati is 14 cm what is it's area
Answer:
diameter=14
radius =14/2=7
area =πr²
22/7×7²154cm²hope it helps
stay safe healthy and happy.Step-by-step explanation:
Area of circle = 2π r²
diameter is 14 cm so radius will be 7 cm
= 2 × 22/7 × 7 × 7
= 44 × 7
= 308 cm²
Find the area of the wrestling mat.
Answer:
804.25
Step-by-step explanation:
The area of a circle = pi(r)^2
Given the diameter, we can find the radius by dividing the diameter in half.
r=16
pi(16)^2 = 804.25
Answer:
803.84 OR 256 pi
Step-by-step explanation:
Ok!
Step 1:
The area of a circle is Pir^2. (Sorry it’s pi r squared, I don’t have the pi symbol or the exponent function on my iPad.)
R is radius. Remember, radius is half the diameter.
32/2=16.
Step 2:
Do 16^2.
You should get 256.
Step 3:
Multiply 256 by Pi. Pi is 3.14. You should get 803.84.
Step 4:
803.84 should be the answer, I THINK (not sure) you can also write your answer as 256 pi. Depends on what your teacher wants. Hope this helps! Next time you can search up how to find the area of a circle, there are lots are tutorials!

Robert invested $7,600 in an account paying an interest rate of 1.9% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $8,600?
Answer:
the answer is 7
Step-by-step explanation:
Compounded Continuously:
A=Pe^rt

Cora and Daniel are both saving money each month. The total amount in their savings accounts is a function of the number of month
they have been saving. Each account is represented below.
Cora: y = 65x + 100, where y represents the total amount and x represents number of months
Daniel:
Answer:
Cora
Daniel
Daniel
Step-by-step explanation:
Forming equation for Daniel's saving from the plot:
Slope, m :
m = y2 - y1 / x2 - x1
m = (300 - 150) / (3 - 1)
m = 150 /2
m = 75
Intercept, c ; value of y when, x = 0
c = 75
Daniel's equation :
y = 75x + 75
Initial amout is described by intercept
Cora's intercept = 100
Daniel's intercept = 75
Rate is described by the slope
Daniel = 75
Cora = 65
So, Daniel is saving at a faster rate ; 75 to Cora's 65
Amount after 6 months :
After 6 months
y = 75*6 + 75 = $525
Cora:
y = 65x + 100
y = 65*6 + 100 = $490

Step-by-step explanation:
Wel and George each have a packet of 20 seeds. They are planting seeds in different rows of a garden. Each row is 10 yards long. Wel plants a seed every 4 feet, starting 4 feet from the end of her row. George plants a seed every 2 yards, starting 2 yards from the end of his row. What is the greatest number of full rows that each person can plant using just their packet of seeds? Enter the answers in the boxes. Wei can plant full rows. George can plant full rows.
Answer:
a) Wel can plant four full roes
b) George can plant five full rows
Step-by-step explanation:
The number of seeds in the packet of seeds Wel and George have, n = 20 seeds each
The length of each row of the garden = 10 yards = 30 feet
The distance between the seeds Wel plants, d = 4 feet
The point at which Wel starts to plant the seeds = 4 feet from the end of the row
The distance between the seeds George plants = 2 yards
The point George starts to plant the seeds = 2 yards from the ends his row
Therefore, we have;
a) The length of each row Wel plants her seeds, l = 10 yd. - 4 ft. = 26 ft.
The number of seeds she plants per row = The whole number part of l/d
l/d = 26 ft./(4 ft./seed) = 6.5 seeds
∴ The number of seeds she plants per row, s = 6 seeds
The number of rows Wels plants her seeds, r = The next whole number of the ratio, n/s =
n/s = 20/6 = 3.[tex]\overline 3[/tex]
∴ The number of rows Wels plants 4 full rows
Therefore;
Using just her packet of seeds, Wels can plant four rows in the garden
b) The length of each row George plants his seed = 10 yd. - 2 yd. = 8 yd.
The number of seeds he plants per row = 8 yd./row/(2 yd./seed) = 4 seeds/row
The number of rows he plants his seeds = 20 seeds/(4 seeds/row) = 5 rows
The number pf rows George plants his seeds = 5 rows
Using just his packet of seeds, George can plant 5 full rows

The length of the arc of semi circle is 15 cm calculate the area of the semi circle ?
Answer:
The area of the semi-circle is 35.8 cm².
Step-by-step explanation:
The length of the arc is given by:
[tex] s = r\theta [/tex] (1)
Where:
s: is the length of the arc of semi-circle = 15 cm
r: is the radius
θ: is the angle in radians
Since we need to calculate the area of the semi-circle, the angle is:
[tex] \theta = \frac{360}{2} = 180 = \pi [/tex]
From equation (1) we can find the radius:
[tex] r = \frac{s}{\theta} = \frac{15}{\pi} [/tex]
Now, the area of the semi-circle is:
[tex] A = \frac{\pi r^{2}}{2} = \frac{\pi (\frac{15}{\pi})^{2}}{2} = 35.8 cm^{2} [/tex]
Therefore, the area of the semi-circle is 35.8 cm².

What is the rate of change of the linear function that has a graph that passes through (9,2) and (3,-1)?
=================================================
Explanation:
Your teacher wants you to find the slope
m = slope
m = (y2-y1)/(x2-x1)
m = (-1-2)/(3-9)
m = -3/(-6)
m = 1/2
----------------
Extra info:
We can think of the slope as
slope = rise/run
and furthermore,
rise = change in y = y2-y1run = change in x = x2-x1Essentially we subtract the corresponding y coordinates together, subtract the x together (in the same order as the y values), then divide the differences.
Tommy had 40 oranges to give to 3 groups of children.
- The first group ate 30% of the total oranges.
- The second group ate 7 of the total oranges.
- The third group ate 1/8 of the total oranges.
How many oranges were left?
Answer:
16
Step-by-step explanation:
1st group = 30% or .3 as a decimal
.3 * 40 = 12
2nd group = ate 7
Third group = 1/8 or .125 as a decimal
.125 * 20 = 5
12 + 7 + 5 = 24
40 -24 = 16
At a large university, 15% of students are left-handed. A psychology professor selects a random sample of 10 students and records L = the number of left-handed students in the sample.
Starting on line 1 of the random-number table, how many left-handed students occur in the first trial of the simulation if we let 00-14 represent left-handed students?
=============================================================
Explanation
We start in the first row at the very left side. The first two digits are the '2' and '4', and they form the value 24. Since 24 is not in the interval from 00 to 14, this means that the first randomly selected student is not left-handed.
The next two digits are 0 and 0. This forms 00 and represents a left-handed student because now we are between 00 and 14. Make a tally of how many left-handed students you count.
As we keep reading across the row, the next two digits are 0 and 7 and they combine to 07. This is another left handed student. However, the student after that is not left-handed since 59 is not in the range from 00 to 14.
Here's a list of all the values we read from the table, and if they're left handed or not:
table value = 24, not left-handedtable value = 00, left-handed (1 so far)table value = 07, left-handed (2 so far)table value = 59, not left-handedtable value = 83, not left-handedtable value = 62, not left-handedtable value = 20, not left-handedtable value = 09, left-handed (3 so far)table value = 15, not left-handedtable value = 18, not left-handedThere are 3 left-handed people in our sample. The table values were: 00, 07, and 09 in that order from left to right.
So that's why the answer is 3.
If you start at another point in the random-number table, then it may be likely that you'll get a different answer. Also, if you decide to read the table in a different way, then you may likely get a different answer.
