Question

Which of the following is closest to the circumference, in inches, of a circle that has a diameter of 12 inches?

Answer 1

37.68 inches

Explanation:

The formula for the circumference of a circle is 2πr.

The radius is 6, and 6⋅2 = 12 (diameter).

3.14 = pi.

12 ⋅ 3.14 = 37.68

Whichever answer is closest to 37.68 is your answer!
