Question

An aquarium tank is built as a cylinder with a radius of 10 ft and a height of 12 feet. If the water weighs 62.43 lb per cubic foot, what is the weight of the water in the aquarium when it is full of water? Use 3.14 for pi and round to the nearest pound.

Answer 1

pi r^2 h * 62.43

Answer 2

Volume = π r^2 h = 3.14 * 10^2 * 12

weight = V * 62.43
