Answer: 175.8 cm^2
Explanation:
The formula for calculating the area of a sector is expressed as
Area = θ/360 x πr^2
where
r is the radius of the circle
θ is the angle subtended at the center
From the information given,
θ = 315
r = 8
π = 3.14
By substituting these values into the formula,
Area of sector = 315/360 x 3.14 x 8^2
Area of sector = 175.8 cm^2
