Question

Please need help very badly.

Find the area of the shaded area.
Round to the nearest tenth

Answer 1

192.5 ft²

Explanation:

Area of the sector

= (360-100)/360 x π(8.35)²

= 158.195 ft²

Area of the triangle

= 1/2 (8.35)(8.35) sin (100)

= 34.3316 ft²

Area of the shaded part

= 158.195 + 34.3316

= 192.5 ft²
