Pls help! I don’t understand bc I’m not smart-

Answer 1

78.5 m²

Explanation:

The formula to find the area of a quarter of a circle:
`(1)/(4) * \pi * r^(2)`, where
`r` is the radius (diameter ÷ 2) and the
`\pi` is alterable.

1) Substitute the given values into the formula.

=
`(1)/(4) * 3.14 * 10^(2)`

2) Solve it.

=
`(1)/(4) * 314`

= 78.5

3) Round it off to the nearest tenth. In this case, it has already been rounded off.
