# Volume of cylinder calculator

To calculate the volume of a cylinder, you can use the formula:

V = πr^2h

where V is the volume, r is the radius of the cylinder base, and h is the height of the cylinder.

To use this formula in a calculator, simply input the values of r and h, and then multiply the result by π.

For example, let’s say you have a cylinder with a radius of 3 cm and a height of 8 cm. Here’s how to calculate its volume:

V = πr^2h V = π(3 cm)^2(8 cm) V = π(9 cm^2)(8 cm) V = 72π cubic centimeters (cm^3)

Therefore, the volume of the cylinder with a radius of 3 cm and a height of 8 cm is 72π cubic centimeters (cm^3), or approximately 226.2 cubic centimeters (cm^3) when rounded to the nearest tenth.

## The steps to calculate the volume of a cylinder:

1. Measure the radius (r) of the cylinder base. If the radius is not given, you can measure it using a ruler or a tape measure.
2. Measure the height (h) of the cylinder. If the height is not given, you can measure it using a ruler or a tape measure.
3. Substitute the values of r and h into the formula for the volume of a cylinder:

V = πr^2h

where π is a mathematical constant approximately equal to 3.14159.

1. Calculate the value of the volume by performing the necessary arithmetic operations.
