Answer:


area = 200.96 \: {units}^(2) \\ circumfrence = 50.24 \: units

Explanation:

The formula to find the area and circumference of a circle is:


area = \pi {r}^(2) \\ circumfrence = 2\pi \: r

*note that pi is 3.14* Therefore the area is:


formula = \pi {r}^(2) \\ 3.14 * {8}^(2) = \\ 3.14 * 64 = 200.96

Therefore the circumference is:


formula = \: 2\pi \: r \\ (2)(3.14)(8) = \\ 3.14 * 16 = 50.24
