The explanation that can be used to informally derive the formula for the volume of a cylinder is: The volume of a cylinder can be found by using the volume of a triangular prism, however, instead of using the base length of the triangle, use the radius of the cylinder.
The formula for the volume of a cylinder can be obtained with the formula:
∨ = πr²h
This is similar to the volume of a triangular prism, which is given by:
The Area of the base triangle × Height.
However, in the case of the volume of a cylinder, the base length of the triangle is not used. The radius of the cylinder is used.
