**Understanding the Volume of a Cylinder: A Step-by-Step Guide** ===========================================================

What is the Volume of a Cylinder?

The volume of a cylinder is a fundamental concept in mathematics, particularly in geometry. It is defined as the amount of space inside the cylinder. The formula for the volume of a cylinder is given by:

V = πr^2h

where V is the volume, π (pi) is a mathematical constant approximately equal to 3.14, r is the radius of the base of the cylinder, and h is the height of the cylinder.

Calculating the Height of a Cylinder

In the given problem, James is asked to calculate the height of a cylinder with a volume of 324π cubic inches and a radius of 12 inches. Let's break down the steps involved in solving this problem.

Step 1: Write Down the Formula for the Volume of a Cylinder

The formula for the volume of a cylinder is given by:

V = πr^2h

In this case, the volume (V) is 324π cubic inches, the radius (r) is 12 inches, and we need to find the height (h).

Step 2: Plug in the Values into the Formula

Substitute the given values into the formula:

324π = π(12)^2h

Step 3: Simplify the Equation

Simplify the equation by evaluating the expression inside the parentheses:

324π = π(144)h

Step 4: Divide Both Sides by π

Divide both sides of the equation by π to get rid of the π term:

324 = 144h

Step 5: Divide Both Sides by 144

Divide both sides of the equation by 144 to solve for h:

h = 324/144

h = 2.25

Therefore, the height of the cylinder is 2.25 inches.
