Step-by-step explanation:
The circumference of a circle can be found using the following formula:
where d is the diameter. We are given the radius, so let's find the diameter.
The diameter is twice the radius.
The radius is 15 feet.
Multiply.
Now we know the diameter. Substitute 30 feet in for d.
We are using 3.14 for pi, so substitute it in.
Multiply.
The circumference of the circle is 94.2 feet.
