Geometry

Volume of a Cylinder Formula: V = πr²h

• r is radius
• h is height

Explanation:

Step 1: Define

Identify variables

r = 2 cm

h = 5 cm

Step 2: Find Volume

1. Substitute in variables [Volume of a Cylinder Formula]: V = (3.14)(2 cm)²(5 cm)
2. Evaluate exponents: V = (3.14)(4 cm²)(5 cm)
3. Multiply: V = (12.56 cm²)(5 cm)
4. Multiply: V = 62.8 cm³

Answer 2

62.8 m^2

Explanation:

The volume of a cylinder is given by

V = pi r^2 h where r is the radius and h is the height

V = (3.14) ( 2)^2 *5

V = 62.8 m^2
