PLS PUT A CORECT ANSWER

Answer 1

Answer:

A = 156.25 pi  cm^2

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

25 pi = 2 * pi *r

Divide each side by 2 pi

25 pi/2 pi  = 2 pi r / 2 pi

12.5 = r

We can find the area by

A = pi r^2

A = pi ( 12.5) ^2

A = 156.25 pi  cm^2
