Geometry

Volume of a Cylinder Formula: V = πr²h

• r is radius
• h is height

Explanation:

Step 1: Define

Identify variables

r = 8 mm

h = 20 mm

Step 2: Find Volume

1. Substitute in variables [Volume of a Cylinder Formula]: V = π(8 mm)²(20 mm)
2. Evaluate exponents: V = π(64 mm²)(20 mm)
3. Multiply: V = 1280π mm³
4. Round: V ≈ 4021 mm³
