Volume = π x 3^2 x 6 = 169.6460033 cubic feet

To convert cubic feet to gallons, you will need to multiply the cubic feet by 7.48052. Therefore, the volume of the cylindrical container in gallons would be:

Volume = 169.6460033 x 7.48052 = 1268.178 gallons

Spherical Containers

Spherical containers are less common, but they are often used for storing gases. To calculate the volume of a spherical container, you will need to know the radius of the container. The formula for calculating the volume of a spherical container is:

Volume = (4/3) x π x Radius^3

For example, if you have a spherical container that is 5 feet in radius, the volume would be:

Volume = (4/3) x π x 5^3 = 523.59877 cubic feet

To convert cubic feet to gallons, you will need to multiply the cubic feet by 7.48052. Therefore, the volume of the spherical container in gallons would be:

Volume = 523.59877 x 7.48052 = 3914.022 gallons
