I have the formula
A fraction • π r^2

Answer:
22.2 ft²
Step-by-step explanation:
The area (A) of a sector is calculated as
A = area of circle × fraction of circle
= πr² × [tex]\frac{50}{360}[/tex]
= π × 7.13² × [tex]\frac{5}{36}[/tex]
= [tex]\frac{7.13^2(5)\pi }{36}[/tex] ≈ 22.2 ft² ( nearest tenth )
