Answer: 54.95 ft^2
Explanation:
The formula for calculating the area of a sector is expressed s
Area = θ/360 x πr^2
where
π is a constant whose value is 3.14
θ is the angle subtended at the center of the circle or the angle o the sector
r is the radius of the circle
From the information given,
r = 15
The total angle in a circle = 360 degrees
θ = 360 - 332 = 28
Area of shaded sector 28/360 x 3.14 x 15^2
Area of shaded sector = 54.95 ft^2
