Answer 1

12.56

Explanation:

1. Circumference equation: 2πr

2. Substitute radius in equation: 2•8π

3. Simplify: 16π, or 50.24

4. Divide by 4, since you only need to find 1/4 of the circumference: 12.56

Answer 2

12.56

Explanation:

The shape is 1/4 of a circle.

The arc length is 1/4 of the whole circle’s circumference.

`C=3.14 * d`

`r=8`

`d=2r\\d=2(8)\\d=16`

`1/4 * 3.14 * 16`

`=12.56`
