Question

A circle has a circumference of 25.12 inches what is the diameter of the circle

Answer 1

8

Explanation:

Recall these two equations for circumference and diameter.

Circumference = 2*pi*radius

Diameter = radius*2

25.12 = 2*pi*radius

Radius = 4

Diameter = 4*2 => 8

Thus the diameter is 8
