Area of a Circle Formula: A = πr²

• r is radius

Step-by-step explanation:

Step 1: Define

Identify variables

r = 6.5 m

Step 2: Find Area

1. Substitute in variables [Area of a Circle Formula]:                                         A = (3.14)(6.5 m)²
2. Evaluate exponents:                                                                                         A = (3.14)(42.25 m²)
3. Multiply:                                                                                                             A = 132.732 m²
4. Round:                                                                                                               A ≈ 132.73 m²
