Question

To the nearest square centimeter, what is the area of the circle below? Use pi = 3.14

Answer 1

`78.5cm^(2)`

Explanation:

`A=\pi r^(2)`

`A=(\pi )(5)^(2)`

`A=78.5`

so I guess rounding it to 79

Answer 2

`radius \: \: r = 5 \: cm \\ area = \pi {r}^(2) \\ = 3.14 * (5) {}^(2) \\ = 78.5 \: {cm}^(2)`
