Question

in the formula $v = pi\times r^{2}\times h$, $r^{2}$ stands for.

Explanation:

In the volume formula $V=\pi\times r^{2}\times h$ for a cylinder, where $V$ is volume, $r$ is the radius of the base - circle, and $h$ is height. The formula for the area of a circle is $A = \pi r^{2}$, so $r^{2}$ is part of the calculation for the area of the circular base.

Answer:

The area of the circular base of a cylinder
