The circumference of a clock is 22 inches what is the radius of a clock

The answer is radius=3.5. To find the radius you can use two methods.

1. Divide the circumference by Pie, that will give you the diameter and since that would be 7 and the radius is half of the diameter it would be 3.5.

2. Divide by he circumference by 2 (Pie) so 22/2Pie would give you 3.5 (radius). These methods are just the backwards process of finding the circumference.

First method used C=2 * (diameter)

Second method used C = 2 * (Pie) * Radius
