A cylinder is a three-dimensional solid with 2 bases, 2 edges, and 3 faces. You have to calculate the volume of a cylinder in cubic units of measure. Using the formula for calculating the volume of a cylinder you can take it out simply and easily. The formula to calculate the volume of a cylinder is: V = Π h r², that is, Pi times height times radius squared. And in this OneHowTo article we want to explain you in detail and with an example How to calculate the volume of a cylinder.
Steps to follow:
1
When calculating the volume of a cylinder, you will need to measure the height (h) of the cylinder, a value that is also sometimes called length.
Let’s take a concrete example to be able to apply the formula so that you better understand how to perform the operations. Thus, we will assume that the height or length of the cylinder is 10 cm.

On the other hand, you must also have the measure of the radius (r) of the cylinder, that is, the distance from the outer edge to the center of the circle that serves as the base of this polyhedral figure.
Make sure that you use the same unit of measure for each dimension, in case they are expressed in different units, you will have to do the conversion to obtain the equivalence.
Continuing with the example, we are going to give the radius a value of 3 cm.

Thus, knowing that the formula for calculating the volume of a cylinder it is:
V = Π h r²
We will only need to know how much the number pi is worth, you remember? Yes, we can round it to 3.14 and, therefore, we only need to substitute each value in the formula. Next, you must calculate the square of the radius (r²), multiplying the value by itself and then multiplying the result of the height by Pi, by the result of the radius squared.
V = 3.14 x 10 x 3² = 3.14 x 10 x 9 = 282.6 cm³
Remember to write your answer on the cubic unit of measure adequate.

So you can understand where the formula to calculate the volume of a cylinder is obtained from:
If you take apart a cylinder in your hands you will have two equal circles and a rectangle, right? First you must use the formula to get the area of a circle which is: A = (Π) (r²)
When you get the area of the circle you multiply it by the height of the cylinder and the result is the cylinder volume. Remember to always be careful with the units of measurement you use in calculations.
