How to Find the Volume of a Right Circular Cylinder

Geometry formulas such as the one to find the volume of a right circular cylinder are helpful and necessary. Students in high school geometry need these formulas, but so do homeowners, stay-at-home moms, engineers and mathematicians. Use this formula for all kinds of practical purposes from measuring household containers to the volume of large fuel tanks.

Difficulty:

Moderately Easy

Instructions

1. Take the measurements for the radius of the circular ends of the cylinder. Use the measurements provided if you are solving a problem in class.

2. Measure and note the height of the cylinder.

3. Find the volume of a right circular cylinder by using the formula V = pi*r^2*h. V equals the volume of the cylinder. Pi is the Greek letter that equals the ratio of the circumference to the diameter of any circle and its value is 3.14159. R is the radius of the circular ends of the cylinder and h equals the height of the cylinder.

4. Apply this geometry formula to solve all your right cylinder volume problems.

Tips & Warnings

• Memorize as many of the basic geometry formulas as you can to avoid having to look them up.
