Volume of a Cylinder Formula: V = πr²h

  • V is volume
  • r is radius
  • h is height

Explanation:

Step 1: Define

Radius r = 2 units

Height h = 16 units

Step 2: Find Volume

  1. Substitute in variables [Volume of a Cylinder Formula]: V = π(2 units)²(16 units)
  2. [Volume] Evaluate exponents: V = π(4 units²)(16 units)
  3. [Volume] Multiply: V = π(64 units³)
  4. [Volume] Multiply: V = 201.062 units³
  5. [Volume] Round: V ≈ 201.06 units³
