Question

A hemispherical tank is filled with water and has a diameter of 22 feet. If water

weighs 62.4 pounds per cubic foot, what is the total weight of the water in a full tank,
to the nearest pounds

Answer 1

173 949 pounds

Explanation:

radius of the hemisphere = diameter / 2 = 11 feet

Volume of the hemisphere = (2/3 * radius^3 * pi) = = (2/3 * 11^3 * pi) = 2.787,639881 ft^3

Total weight = volume of the hemisphere * 62.4 = 173,948.728592
