Question

The radius of a circle is 3 feet. What is the circles circumference?

Answer 1

Answer: 6
`\pi` feet, or approximately 18.8 feet

Explanation:

Use the equation
`C = 2\pi r` to calculate circumference.

`C = 2\pi (3)\\C = 6\pi`

Answer 2

C = 6pi ft or approximately 18.84 ft

Explanation:

The circumference of a circle is found by

C = 2*pi*r

C = 2*pi *3

C = 6pi

If we approximate pi

C = 6 (3.14)

C =18.84 ft
