Volume of Cylinders, Cones & Spheres

Apply the three key volume formulas with π.

Step 1 · Learn

Walkthrough

Read this first — it covers the idea in plain language with a worked example.

Worked example

Find the volume of a cylinder with radius 3 and height 5 (use π ≈ 3.14).

Tip

A cone holds exactly one-third of the cylinder with the same base and height — that's where the 1/3 comes from.

Step 2 · Watch

A short video that walks through this topic.

Khan Academy

Find the volume of a cylinder using V = πr²h.

Step 3 · Practice

Try a worksheet or work through some problems before the quiz.

Step 4 · Check
