Answer:

A = 225 pi unit^2

Step-by-step explanation:

The circumference of a  circle is 30 pi

C = pi *d

30 pi = pi*d

Divide each side by pi

30 pi/pi = pi d/ pi

30 =d

The diameter is 30

We need to find the radius for area

d= 2r

30 = 2r

Divide by 2

30/2 = 2r/2

15 =r

The area of a circle is

A = pi r^2

A = pi (15)^2

A = pi 225

A = 225 pi unit^2
