Question

There are approximately 7.5 gallons of water in 1 cubic foot. If a spherical water tank has a diameter of 24 feet, about how many gallons of water will it hold?

Answer 1

`54,286.88` gallon

Explanation:

Volume of a sphere is given by `4/3pir^3`, where `pi=3.1416`.

Hence spherical water tank will hold

`4/3xx3.1416xx(24/2)^3=4/3xx3.1416xx12xx12xx12` or

`4xx3.1416xx4xx12xx12=7238.25` cubic foot of water

or `7238.25xx7.5=54,286.88` gallon
