4.186 feet cubed or 7234.56 inches cubed

Since the diameter of a sphere or circle is equal to the radius times two, find the radius.

#2/2 = 1#

Now that we have the radius, plug it into the equation for volume.

#4/3 * 3.14 * (1)^3#

And simplify.

#4.186666 * 1#

#4.186# feet#^3#

If you wanted the answer in inches, convert the radius to inches and plug that in instead.

#4/3 * 3.14 * (12)^3#

#4.186666 * 1728#

#7234.55885# inches #^3#
