Question

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

Answer 1

Answer:

$circumference = 2\pi \: r \\ = 2 \times \pi \times 22 \\ = 44\pi \: inches$

Answer 2

Answer:

The circumference is 44 pi.

Step-by-step 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.
