Question

A circle has a radius of 10 ft. What is its circumference?
Use 3.14 for Ti, and do not round your answer. Be sure to include the correct unit in your answer.

Answer 1

Circumference of a circle = pi x diameter

pi = 3.14

diameter = radius x 2
diameter = 10 x 2
diameter = 20

Circumference = 3.14 x 20
Circumference = 62.8 ft

Answer 2

Answer:

62.8 ft

Step-by-step explanation:

Circumference = 2πr

2 * 3.14 * 10 = 62.8
