Geometry

Volume of a Cylinder Formula:
`\displaystyle V = \pi r^2h`

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

Explanation:

Step 1: Define

Radius r = 2 ft

Height h = 7 ft

Step 2: Solve for V

1. Substitute in variables [Volume of a Cylinder Formula]:
   `\displaystyle V = \pi (2 \ ft)^2(7 \ ft)`
2. [Volume] Evaluate exponents:
   `\displaystyle V = \pi (4 \ ft^2)(7 \ ft)`
3. [Volume] Multiply:
   `\displaystyle V = 28 \pi \ ft^3`
