Question

Given a circle with a radius of 22 inches, what is the circumference in terms of π?

Answer 1

The circumference is 44 pi.

Explanation:

You have to use the formula, C=2 Pi R but since it's in terms of pi, we can not include pi in the equation. 2 times r (radius) is 44, therefor the answer is 44 pi.

Answer 2

`circumference = 2\pi \: r \\ = 2 * \pi * 22 \\ = 44\pi \: inches`
