Answer:
12.56
Step-by-step explanation:
The shape is 1/4 of a circle.
The arc length is 1/4 of the whole circle’s circumference.
[tex]C=3.14 \times d[/tex]
[tex]r=8[/tex]
[tex]d=2r\\d=2(8)\\d=16[/tex]
[tex]1/4 \times 3.14 \times 16[/tex]
[tex]=12.56[/tex]
Answer:
12.56
Step-by-step 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
