Here is the formula for finding area of a sector:
A = [tex]\pi r^{2}[/tex] × 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:
[tex]\frac{25\pi }{2} unit ^{2}[/tex]
You should find 39.26991 as your answer (or any number rounded according to the value of pi)
