se the value 3.14 for , and do not round your answers. Be sure to include the correct units in your answers.

Answer 1

18.84 m

Explanation:

Diameter=3x2=6m

Circumference=pi×diameter=3.14x6=18.84 m

Answer 2

CIRCUMFERENCE

`c = 2\pi \: r \\ = 2 * 3.14 * 3 \\ =6.2 8 * 3 \\ =18.8 4m`

Area

`area = \pi {r}^(2) \\ = 3.14 * 3 * 3 \\ =9.4 2 * 3 \\ =28.2 6 {m}^(2)`
