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
I'm stuck with this aswell however I think you can't draw a square with a 8cm2 area, sorry.

Conversion factor to convert in2 into ft2 (1 ft2/144 in2). Area of a brick=7.63 in X 2.25 in = 17.1675 in2 or 17.17 in2. 17.17 in2 X 1 ft2/144 in2 = 0.119236111 ft2 or 0.12 ft2 area of brick in sq ft. 225 ft2/(0.12 ft2/brick) = 1875 bricks It will take 1875 bricks (7.63 in X 2.25 in) to fill a 225 ft2 area.
1 inch = 2.54 centimeters(1 in x 1 in) = 1 in2 = (2.54 cm x 2.54 cm) = 6.4516 cm210.4 in2 = (10.4 x 6.4516) = 67.09664 cm2
