a. What is the circumference of the
largest circle that can be cut from a
square measuring 30 cm on a side?
Use 3.14 for T.


b. What percent of the perimeter of the
square is the circumference of the
circle?

Answers

Answer 1

Answer:

Step-by-step explanation:

a. The diameter of the circle will be 30 cm

So circumference is 3.14 * 30  = 94.2 cm.

b. Required percentage = (94.2) * 100 / (4*30)

= 78.5%.

A rectangle of length 14 cm and breadth 7 cm is folded into a right circular cylinder. How many revolutions does the cylinder need to make to cover an area of 784 sq.Cm

Answers

Answer:

n = 8

Step-by-step explanation:

Given that,

Length and breadth of a rectangle are 14 cm and 7 cm.

The area of rectangle is given by :

[tex]A=l\times b\\\\A=14\times 7\\A=98\ cm^2[/tex]

Let n be the number of revolutions the cylinder need to make to cover an area of 784 sq.cm.

So,

[tex]n=\dfrac{784}{98}\\\\n=8[/tex]

Hence, there are 8 revolutions.

Find the center and the radius of the circle with endpoints (−1, −1), (−25, −11) . Round to the nearest tenth if necessary.

Answers

Answer:

Center- (-13, -6)

Radius = 12 units

Step-by-step explanation:

The radius is gotten by first taking the distance between the point using the distance formula

D = √(-11+1)²+(-25+1)²

D = √(-10)²+(-24)²

D = √100 + 576

D = √676

D = 26

This gives the diameter of the circle

Radius = diameter/2

radius = 26/2

Radius = 12

The center of the circle is the midpoint of the coordinate

X = x1+x2/2 and Y = y1+y2/2

X = -1 - 25/2

X = -26/2

X = -13

Y = -1 - 11/2

Y = -12/2

Y  = -6

Hence the center is at (-13, -6)

Answers

Answer:

No Solutions

Step-by-step explanation:

The two points are (3,2) and (-2,-2)

Slope is y change over x change.

So... -2-2 over -2-3 equals to -3-(-2) over -2-(-2).

That is -3+2 over -2+2 which is -2 over 0.

You can't divide by zero so the slope is "NoSolutions"

guys, determine the equation of each line, given the information below:
Passing through the points D(2, 3) and E(-2, -4)

Answers

Answer:

The equation is;

4y = 7x + 2

Step-by-step explanation:

The general equation of a straight line is;

y = mx + b

where m is the slope and b is the y-intercept

m = (y2-y1)/(x2-x1)

(x1,y1) = (2,3)

(x2,y2) = (-2,-4)

m = (-4-3)/(-2-2) = -7/-4 = 7/4

So we have the equation as;

y = 7x/4 + b

To

get the value of b, we will substitute any of the points (let us use 2,3)

We simply substitute 2 for x and 3 for y

We have this as:

3= 7(2)/4 + b

3 = 7/2 + b

b = 3-7/2 = -1/2

So we have the equation as;

y = 7x/4 + 1/2

multiply through by 4

4y = 7x + 2
