The circumference of a circle is 15π centimeters. what is the area of the circle in terms of π?

a. 7.5π cm²

b. 15π cm²

c. 56.25π cm²

d. 225π cm²

C.56.25π cm²

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

15 pi = 2 * pi *r

Divide each side by pi

15 = 2r

Divide by 2

15/2 = 2r/2

7.5 = r

We want to find the area

A = pi r^2

A = pi (7.5)^2

A = pi *56.25

A = 56.25 pi

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
