What is the volume of this figure?

Answer:

area of base = pi x radius^2 = (ill use 3.14 as pi)

3.14 x 7^2 = 153.86 in^2

height = 12

circunference of base = 2 x pi x radius or pi x diameter (diameter = 2 x radius) = 3.14 x 14 = 43.96 in

surface area = perimeter of base x height (lateral area) + 2 x area of base

= 43.96 x 12 = 527.52 + 2(153.86) = 835.24

hope that answers your question

(be careful, i generally use 3.14 as pi, but if your question says to use other forms as pi, then just replace pi as what the question asks, ive given you the formulas on how to calculate area and circumf., so i hope it should be easier...)

Answer:

72 sq cm

Step-by-step explanation:

Surface area of the cuboid is 2*(lb+bh+lh)=2*(12+18+6)=2*36=72

Answer:

36 sq cm

Step-by-step explanation:

This prism is formed by rectangles, and to find the area of a rectangle you have to multiply its sides. So, to find the surface area, you find the area of each rectangle and after add it all:

3×2 = 6 sq cm, and your have two of this rectangles

6×2 = 12 sq cm, and you also have two of this

3×6 = 18 sq cm, and also have two of this

6 + 12 + 18 = 36 sq cm

Answer:

18.33333333%. Please mark as brainliest if I’m Correct. :)

Step-by-step explanation:

Answer:

surface area of a square = 2 ( lb + bh + hl )

given that,

length = 8cm

breadth = 10cm

height = 15 cm

surface area = 2 ( 8* 10 + 10*15 + 15*8 )

                     = 2 ( 80 + 150 + 120 )

                     = 2 * 350

                     = 700 [tex]cm^{2}[/tex]

Answer: Duncan got 22 questions correct

Step-by-step explanation:

Total questions in quiz = 55

Total answered correctly by Duncan = 40% of 55

Total answers he got correct = 40% of 55

= 40/100×55

= 22

Therefore Duncan got 22 questions correct

Step-by-step explanation:

Area of the rectangle = 9×6 = 54 m²

Area of the path is also 54 m²

so total area of the bigger rectangle is 54+54 = 108 m²

now the ratio of length to width is 9:6 or, 3:2

so, for 108 m²

(3x)(2x) = 108

6x²=108

x²=18

x=3√2

So length = 3x = 9√2 and width = 2x = 6√2

There were 42 people who are fishing if the ratio of people watching whales to people fishing was five to seven.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

We have been given that the ratio of people watching whales to people fishing was five to seven if there were 72 people.

Let the number of people who watch whales would be 5x

And the number of people who are fishing would be 7x

According to the given condition, the required solution would be as:

⇒ 5x + 7x = 72

⇒ 12x = 72

⇒ x = 6

So the number of people who are fishing = 7 × 6 = 42

Therefore, there were 42 people who are fishing.

Answer:

197 pounds of cans

Step-by-step explanation:

Find how many pounds of cans they have collected by subtracting 8 from both of their barrel weights:

115 - 8

= 107

98 - 8

= 90

Add these two weights together:

107 + 90

= 197

So, they collected 197 pounds of cans

Answer:

Step-by-step explanation:

If angle 2 is 75, the other angles that are also 75 are angles 4 (it's vertical to angle 2), angle 6 (it's corresponding to angle 2), angle 8 (it's alternate exterior to angle 2). All the other angles measure 180 - 75 which is 105.

Answer:

4m/3m

Step-by-step explanation:

1km = 1000m

750m : 1km

750m : 1000m

Reduce ratio in simplest form.

HCF of 1000 and 750 is 250

750  ÷ 250 / 1000  ÷ 250

= 4/3

Hence, the simplest form of the ratio 750m : 1km is 4m/3m

Answer:

sqrt( 97)

Step-by-step explanation:

To find the distance between 2 points

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

   = sqrt( (3-7)^2 + (8 - -1)^2)

    = sqrt( ( -4)^2 + (8+1)^2)

    = sqrt( 16+9^2)

   = sqrt(16+81)

  = sqrt( 97)

Answer:

exterior angle property use ...

the exterior angle of an angle is equal to sum of rest 2 interior angles in a triangle

155 = 60 + x

x = 155 - 60 = 95

The missing angle x in the triangle is 95 degrees.

Here, we have,

from the given figure we get,

one angle of the triangle is: 180- 155 = 25 degrees.

To find the missing angle x in the triangle, we can use the fact that the sum of the angles in a triangle is always 180 degrees.

In this case, we are given two angles of the triangle: 25 degrees and 60 degrees.

Let's denote the missing angle as x.

To find x, we can subtract the sum of the given angles from 180 degrees:

x = 180° - (25° + 60°).

Simplifying the expression inside the parentheses:

x = 180° - 85°.

Subtracting:

x = 95°.

Therefore, the missing angle x in the triangle is 95 degrees.

Answer: q -> p

Step-by-step explanation: You've got it right! To find the converse, you switch the first and second halves of the statement and keep it positive.

Answer:

q→p

Step-by-step explanation:

The converse is a type of mathematical statement that changes the conditional statement. If the conditional statement is p→q then the converse is q→p. This is because the converse of a statement reverses any type of statement. For example, if the conditional statement is: if an angle has 90 degrees, then it is a right angle. Then, the converse would be: if an angle is a right angle, then it has 90 degrees.
