The answer depends on whether the 4 foot measure is the radius or the circumference.
For a 3 foot diameter pipe, 52.9 US gallons per foot of length.
6 ft x 2 ft is a measure of area in 2 dimensional space - even if you choose to call it a diameter. A metre is a measure of distance and cannot be used to measure an area.
A round pool with a 10-foot diameter and a 3-foot depth can hold up to 1,762 gallons of water.
A linear foot is the same as a foot. So, an 18-foot diameter circle would measure 18 linear feet in diameter!
The answer depends on what "3 foot" refers to!

The volume of the ball, right? You can measure the ball's diameter, divide by 2 to get the radius, then use the formula for the volume of a sphere. If you find it difficult to measure the diameter, you can also measure the circunference, and divide that by (2 x pi) to get the radius.
6 ft x 2 ft is a measure of area in 2 dimensional space - even if you choose to call it a diameter. A metre is a measure of distance and cannot be used to measure an area.
Most people just measure the circumference and divide by 3.14 (approximate pi) to find the (approximate) diameter.
