Question

Given a circle with a diameter of eight what is the circumference

Answer 1

Explanation:

you find that by the formula
`2\pi r`

meaning that (
`2(\pi) (8/2)`

then
`2\pi (4)`

C = 25.13

Answer 2

The answer is 25.12

Explanation:

Using the circumference formula (2PiR)

2 * 3.14 * 4

(4 because the radius is half the diameter)

Multiply them all and you get 25.12
