Question

Find the approximate value of the circumference of a circle with the given radius. Use = 3.14. Round your answer to the nearest tenth.

4 inches

anonymous · Answer

The radius is 4 inches?

anonymous · Answer

Well, the Circumference formula is C = pi * d

pi is 3.14
d is the diameter

if the radius is 4, the diameter is 8 because the diameter is twice the size of the radius.

So your answer will be:

C = 3.14 * 8

C = 25.12

After you round it to the nearest tenth it's 25.1
