Question

If the radius of a circle is 8 feet, please find:

-The diameter
-The circumference
-The area

Answer 1

Explanation:

Radius (r) = 8 feet

`Diameter(d) = 2 * radius \\= 2 * 8 = 16 \: feet \\ \\ circumference \\ c = \pi \: d = 3.14 * 16 = 50.24 \: feet \\ \\ area = \pi {r}^(2) \\ = 3.14 * {8}^(2) \\ = 3.14 * 64 \\ = 200.96 \: {feet}^(2)`
