General Formulas and Concepts:

Pre-Alg

• Order of Operations: BPEMDAS

Geometry

• Area of a Circle: A = πr²
• d = 2r

Explanation:

Step 1: Define

d = 4 m

Step 2: Find r

1. Substitute: 4 = 2r
2. Isolate r: 2 = r
3. Rewrite: r = 2 m

Step 3: Find Area

1. Substitute: A = π(2)²
2. Substitute: A = (3.14)(2)²
3. Evaluate: A = (3.14)(4)
4. Multiply: A = 12.56 m²
