Question

The diameter of a circle is 28 meters. What is the circle's circumference?

Answer 1

28π meters or approximately 87.96 meters.

Explanation:

Divide 28 by 2 to find the radius is 14 meters. Use the formula C = 2πr to find that the answer is 28π; C = 2π(14) -> 28π.

Answer 2

87.96

Explanation:

C=2πr

d=2r

Solving for C

C=πd=π·28≈87.96
