Introduction

The formula for the volume of a right cylinder is given by $V = \pi r^2 h$, where $V$ represents the volume, $r$ is the radius, and $h$ is the height of the cylinder. This formula is a fundamental concept in mathematics, particularly in geometry and calculus. In this article, we will focus on solving for the radius $r$ in the given formula.

Understanding the Formula

The formula $V = \pi r^2 h$ is a mathematical representation of the volume of a right cylinder. The volume of a cylinder is directly proportional to the square of its radius and its height. The constant $\pi$ is a mathematical constant that represents the ratio of a circle's circumference to its diameter. In this formula, $\pi$ is used to calculate the volume of the cylinder.

Solving for Radius

To solve for the radius $r$, we need to isolate $r$ in the formula $V = \pi r^2 h$. We can start by dividing both sides of the equation by $\pi h$:

$$\frac{V}{\pi h} = r^2$$

Next, we take the square root of both sides of the equation to solve for $r$:

$$r = \sqrt{\frac{V}{\pi h}}$$

However, this is not the only possible solution. We can also express the solution in terms of $\pi$ and the square root of $Vh$:

$$r = \pi \sqrt{\frac{V}{\pi^2 h}}$$

Simplifying the expression, we get:

$$r = \pi \sqrt{\frac{V}{\pi h}}$$

$$r = \pi \sqrt{\frac{V}{\pi} \frac{1}{h}}$$

$$r = \pi \sqrt{\frac{V}{\pi} \frac{1}{h}}$$
