Understanding Cone Volume Calculations

A cone is a three-dimensional geometric figure with a circular base that tapers to a point called the apex. The volume of a cone is calculated using the formula V = (1/3)πr²h, where:

  • r is the radius of the base
  • h is the height from the base to the apex
  • Ï€ (pi) is approximately 3.14159

Conical Frustum Volume

A conical frustum is the portion of a cone that lies between two parallel planes. Its volume is calculated using the formula V = (1/3)πh(R² + r² + Rr), where:

  • R is the radius of the base
  • r is the radius of the top
  • h is the height between the parallel planes
