Question

find the circumference of each circle use 3.14 for the value of pi round your answer to the nearest tenth if necessary

Answer 1

Answer: 23.2 inches

Work Shown:

C = 2*pi*r

C = 2*3.14*3.7

C = 23.236

C = 23.2 when rounding to the nearest tenth

The result is approximate since pi = 3.14 is approximate.

The circumference is the perimeter around the circle. Think of it like the amount of fencing needed to enclose the circle.
