Question

Which equation listed below, when solved, shows how to find the circumference of a circle if the diameter is 6 inches? Use 3.14 for pi

Answer 1

A 3.14x6

Explanation:

Answer 2

C = π(6)

C = 6π

C = 18.84

Explanation:

The circumference is the distance around the circle. It relates the number of times the diameter will encircle the circumference as 3.14 or π. As a result, the formulas for the circumference of a circle are C = 2πr or C = πd. The information given is the diameter so use C = πd by substituting d = 6.

C = π(6)

C = 6π

C = 18.84
