Introduction

In mathematics, solving for the height of a cylinder is a common problem that involves using the formula for the volume of a cylinder. The formula for the volume of a cylinder is given by V = πr^2h, where V is the volume, π is a constant, r is the radius, and h is the height. In this article, we will walk through the steps to solve for the height of a cylinder using the given volume and radius.

The Problem

Louise calculated the height of a cylinder that has a volume of $$488 \pi$$ cubic centimeters and a radius of 9 centimeters. Her work is shown below.

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

Step 1: Substitute the Given Values

The first step is to substitute the given values into the formula for the volume of a cylinder.

${ 488 \pi = \pi (9^2) h }$

In this step, we have substituted the given volume of $$488 \pi$$ cubic centimeters and the radius of 9 centimeters into the formula.

Step 2: Simplify the Equation

The next step is to simplify the equation by evaluating the expression inside the parentheses.

${ 488 \pi = \pi (81) h }$

In this step, we have simplified the equation by evaluating the expression inside the parentheses.

Step 3: Divide Both Sides by π

The next step is to divide both sides of the equation by π to isolate the term involving the height.

${ 488 = 81h }$

In this step, we have divided both sides of the equation by π to isolate the term involving the height.

Step 4: Divide Both Sides by 81

The final step is to divide both sides of the equation by 81 to solve for the height.

${ h = \frac{488}{81} }$

In this step, we have divided both sides of the equation by 81 to solve for the height.

Conclusion

In this article, we have walked through the steps to solve for the height of a cylinder using the given volume and radius. We have used the formula for the volume of a cylinder and substituted the given values into the formula. We have then simplified the equation and isolated the term involving the height. Finally, we have solved for the height by dividing both sides of the equation by 81.

The Final Answer

The final answer is:

${ h = \frac{488}{81} }$

The Height of the Cylinder

The height of the cylinder is $$\frac{488}{81}$$ centimeters.
