Area of triangle= 1/2(bh)
So u do the reverse to find the base
48 x 2 which equals 96
Then u divide
96 divided by 8 = 12
Length of base equals 12
Answer:
≈ 93.06 cm²
Step-by-step explanation:
Subtract the area of the rectangle from the area of the circle
area of circle = πr² = π × 8² = 64π cm²
area of rectangle = 12 × 8 = 108 cm²
Thus
shaded area = 64π - 108 = 201.062 - 108 ≈ 93.05 cm² ( nearest hundredth )
