please help!!! what is the area of the sector formed????

Answer:
62.8 ft²
Step-by-step explanation:
The area (A) of the sector is calculated using the formula
A = area of circle × fraction of circle
= π × 4² × [tex]\frac{\frac{5\pi }{2} }{2\pi }[/tex]
= π × 16 × [tex]\frac{5}{4}[/tex]
= π × 20 = 20π ≈ 62.8 ft²
