Answer:
The area of the roof: ≈2287.44 ft^2, the lateral area of the roof:≈1580.58 ft^2
Step-by-step explanation:
The area of the roof is computed by the equation of the area of a cone:
A = πr(r + )
(r: radius, h: height, πr^2 is the area of the base of the cone, πr is the lateral area of the cone). So:
A = ≈ 2287.44 ft^2.
As I stated earlier, the lateral area of the roof can be computed:
A=
≈ 1580.58 ft^2.
