Here is the formula for finding area of a sector:
A =
× θ° ÷ 360°
where theta is the angle of the sector you wish to find, and r is the radius of the circle.
Substitute the numbers in and you get:
![(25\pi )/(2) unit ^(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/gqxzd33cihwbue6r0xqdmf35879dhscakj.png)
You should find 39.26991 as your answer (or any number rounded according to the value of pi)
