Question

In the formula for the volume of a cylinder, how is the area of the base determined?

Answer 1

Answer:

area of base =  $\pi r^2$

where 'r' is the radius

Step-by-step explanation:

Volume of the cylinder formula = $\pi r^2h$

volume of cylinder = area of base * height

The base of a cylinder is a circle. so we use the area of circle for the base of cylinder while finding volume

We know area of the circle is $\pi r^2$

So area of the base of cylinder is  $\pi r^2$

To find volume of the cylinder , we multiply the base of the cylinder with height

To determine the base of the cylinder we need radius of the cylinder

area of base =  $\pi r^2$

where 'r' is the radius
