Answer:

Circumference = 30π inches

Explanation:

The formula for the circumference of a circle is given by:

C = πd, where

  • C is the circumference,
  • and d is the diameter.

Since the diameter is simply twice the radius, we can rewrite the circumference formula in terms of r (the radius):

C = π * 2r

C = 2πr

Now we can find the circumference of the circle in terms of π by substituting 15 for r in the circumference formula:

C = 2π * 15

C = 30π

Thus, the circumference of the circle is 30π inches.
