Hemiphere
Hemisphere
A 3D shape bounded by a half cut portion of a sphere and a flat circular base.
Properties
  1. It is 3D counterpart of a semicircle.
  2. It has 1 curved surface and 1 flat circular base.
Curved Surface Area of Hemisphere (CSA)
CSA = 2 π r2
r: radius of the hemisphere
Total Surface Area of Hemisphere (TSA)
TSA = 3 π r2
r: radius of the hemisphere
Volume of Hemiphere (V)
V =
2 3
π r3
r: radius of the hemisphere
Volume of Spherical Shell of Hemisphere (Vshell)
Vshell =
2 3
π (R3 − r3)
R: outer radius, r: inner radius of the hemisphere
