V = πr^2h
2007-02-23 20:38:03 · answer #1 · answered by Helmut 7 · 0⤊ 0⤋
The formula is V = pi * r^2 * h
or: Pi times the radius squared times the height.
For example, if the radius were 2 and the height 4 centimeters, the volume would be about 50.256 square centimeters.

Volume of cylinder = (pi)r^2h, where,
pi = 22/7
r = radius of the base, and,
h = height i.e., length of the cylinder.
Let r & h, each, be in cm, so that the volume will be in cc.

Since the area of a cross section is always the same, the volume is just the height times the area of the base.
And the area of the base is of course pi r^2.

Not everyone knows or remembers formulas for volume, but for a regular cylinder, (Top of tube is same size as bottom)
Halve the diameter of the top/bottom of the cylinder and multiply that by itself.(30 millimeters/inches/yards/kilometers etc diameter = 15X15)
Multiply that by 3.142, Don't ask why, just do it!
Then multiply THAT by the height of the cylinder.
One of the biggest mistakes people make is inconsistent values, such as measuring diameter in milimeters but multiplying height by centimeters etc.

if the cylinder has a height of h and a radius of r
the volume is V= pi*r^2*h

<>V = pi*r^2*h for a round-base cylinder.
