How to Calculate Hemisphere

What is Hemisphere?

A hemisphere calculator computes volume, curved surface area, and total surface area from the radius.

Formula

Volume = (2/3) × π × r³

Step-by-Step Guide

  1. 1Volume = (2/3) × π × r³
  2. 2Curved surface area = 2 × π × r²
  3. 3Total surface area = 3 × π × r² (curved + flat circular base)
  4. 4Diameter = 2r

Worked Examples

Input
Radius = 5 cm
Result
Volume = 261.80 cm³; Total SA = 235.62 cm²
