Answer:
A = 225 pi unit^2
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
