Answer:

78.5 m²

Step-by-step explanation:

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

1) Substitute the given values into the formula.

= $\frac{1}{4} * 3.14 * 10^{2}$

2) Solve it.

= $\frac{1}{4} * 314$

= 78.5

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