Question

What is this circles circumference?

Answer 1

25.12

Explanation:

`2\pi(r)`

First divide the diameter by 2

so... 4 is the radius

`(8)/(2)`

Then plug in 4 for r

`plug \: in \: 3.14 \: for \: \pi`

And multiple using the equation

2(3.14)(4)

6.28(4)

25.12

Answer 2

C = 25.12

Explanation:

The circumference of a circle is given by

C = pi*d

C = 3.14 * 8

C = 25.12
