1 ft2 = 144 in2 (12 inches x 12 inches), so divide by 144: (360 in2)/(144 in2/ft2) = 2.5 ft2
1 sq ft = (12in x 12in) = 144 in2 2 sq ft = 288 in2 2.25 sq ft = 324 in2
A circle with circumference 30 in has area = 302 ÷ (4π) ≈ 71.6 in2 < 100 in2 so a square of area 100 in2 cannot fit inside it.
V= 3.14r2hSubstitute the values...2503 in3 = 3.14 X 52 X h2503in3/3.14= 25 in2 h797.13 in3 = 25 in2 h797.13 in 3 / 25 in2 = h31.88 in = h
