Whats the circumference in terms of pi?

Answer & Step-by-step explanation:

First, we must know the formula for finding the circumference of a circle.

Circumference = dπ

(d) represents your diameter. In order to find the diameter, you have to multiply the radius by 2 because the radius is half the size of the diameter.

The radius we are given is 15. So well do 15 multiplied by 2.

15 * 2 = 30

Now, since we have ti put the answer in terms of pi, then you are just going to leave 30 as it is and add the pi symbol.

C = 30π
