A capsule is a cylinder with hemispheres on both ends.

Capsule Formulas

Volume V = πr2((4/3)r + a)

Surface S = 2πr(2r + a)

Circumference C = 2πr

For example, When a = 2, r = 3

  1. To calculate V, use the following formula: πr2((4/3)r + a). When you substitute a and r for their values, you get π(32)((4/3)3 + 2), which equals 169.646 m3.
  2. To calculate S, use the following formula: 2πr(2r + a). When you substitute a and r for their values, you get 2π3(2(3) + 2), which equals 150.79645 m2.
  3. To calculate C, use the following formula: 2πr. When you substitute r for its value, you get 2π3, which equals 18.84956 m.
