Volume of cylinder calculator
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:
- 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.
- Measure the height (h) of the cylinder. If the height is not given, you can measure it using a ruler or a tape measure.
- 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.
- Calculate the value of the volume by performing the necessary arithmetic operations.
