Geometry

Volume of a Cylinder Formula: V = πr²h

• r is radius
• h is height

Explanation:

Step 1: Define

r = 4 cm

h = 10 cm

Step 2: Find Volume

1. Substitute in variables [Volume of a Cylinder Formula]: V = (3.14)(4 cm)²(10 cm)
2. Evaluate exponents: V = (3.14)(16 cm²)(10 cm)
3. Multiply: V = (50.24 cm²)(10 cm)
4. Multiply: V = 502.4 cm³
