The circumference of a circle is 15 pie what is the area of the circle in terms of pie

Step-by-step explanation:

We are given the circumference. The formula for circumference is

C = πd where d is the diameter and C is the circumference.

We are given C = 15π, so we have ...

15π = πd

Solving for d gives us ...

15 = d (divide by π on both sides)

The formula for area of a circle is

A = π (r²) where A is the area, and r is the radius

The radius is half of the diameter, so we divide 'd' by 2 to get the radius ...

r = d/2 = 15/2 = 7.5

The area of the circle is ...

A = π (7.5) ²

A = 56.25π units²
