Hemisphere Calculator
Find a hemisphere’s volume, curved area and total area including its base.
Your numbers
Physical volume
Use consistent units. The result follows the assumptions you enter.
Scenario comparison
Up to three snapshots in this tab. Loading one replaces the current inputs.
Formula
Use V = 2πr³/3, C = 2πr² and S = 3πr². r is radius, V is hemisphere volume, C is curved area, and S includes the circular base.

Scope and limitations
Use consistent units. The result follows the assumptions you enter.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
