Question

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

Answer 1

Do you mean by pi (3.14) ? Because you have to multiply 3.14 by 15 and then you will get the answer

Answer 2

The circumference of a circle is modeled by C=pi*d

Based on what's given d=15

We want the area, which is modeled by A=pi*r^2

R is 7.5 since the radius is half the length of the diameter.

Square the radius. This gives you 56.25

Now times that value by pi.

The area of the circle is approximately 176. 71 units squared.
