Hi there! Last week, I discussed how to find the area of a circle. The answers to the problem from last week can be found on the ‘It All Adds Up’ page. Today, I now want to show you how to find the volume of a cylinder. The correct formula is:
To clarify, here is what each letter stands for:
V- the total volume of the cylinder
R²- the radius of the circle on one end of the cylinder multiplied by itself
H- the height of the cylinder
This diagram shows how you find the volume of a cylinder:
We start by substituting for pi, the radius squared, and the height of the cylinder. After we square the radius, we can use multiplication to find the volume of the cylinder.
