Question

Find the area and the circumference of the circle. Round your answers to the nearest hundredth.

area:
square units

circumference:
units

Answer 1

`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`
