Jak vypočítat Torus

Co je Torus?

A torus is the 3D shape of a donut or ring. It is formed by rotating a circle of radius r around an axis at distance R from the circle's centre. The inner hole appears when R > r.

Vzorec

Volume = 2π² × R × r²
R
radius of the tube itself — radius of the tube itself

Průvodce krok za krokem

  1. 1R = distance from the centre of the tube to the centre of the torus
  2. 2r = radius of the tube itself
  3. 3Volume = 2π² × R × r²
  4. 4Surface area = 4π² × R × r
