A = 12.56 m²

General Formulas and Concepts:

Pre-Alg

  • Order of Operations: BPEMDAS

Geometry

  • Area of a Circle: A = πr²
  • d = 2r

Step-by-step 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
