What is the area of a square with a radius of 17 ft
It is square ft.
Perimeter=28 ft Area=49 square ft
Volume of this pyramid is (area of base) x (height) / 3. The area of the base (square) is (edge)2 So (21 ft)2 * (18 ft)/3 = 26586 cubic feet
12 in = 1 ft area = length x width = 31 ft x (7 + 7 ÷ 12) ft = 235 1/12 sq ft ≈ 235.083 sq ft
