The circumference of a circle is 65 pi. In terms of pi, what is the area of the circle?

A) 600 pi
B) 936.5 pi
C) 950.25 pi
D) 1056.25 pi

A =1056.25 pi

Step-by-step explanation:

The circumference is given by

C = 2*pi*r

65 pi = 2*pi*r

Divide each side by 2 pi

65 pi /2 pi = 2*pi*r/2pi

32.5 = r

To find the area

A = pi * r^2

A = pi *(32.5)^2

A =1056.25 pi

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
