Question

What is the area of a circumference of 22pi

Answer 1

Answer:

A = 121π

General Formulas and Concepts:

Pre-Algebra

• Order of Operations: BPEMDAS
• Equality Properties

Geometry

• Circumference: C = 2πr
• Area of a Circle: A = πr²

Step-by-step explanation:

Step 1: Define

C = 22π

Step 2: Find radius r

1. Substitute:                    22π = 2πr
2. Isolate r:                        11 = r
3. Rewrite:                         r = 11

Step 3: Find Area

1. Substitute:                    A = π(11)²
2. Evaluate:                       A = 121π

And we have our final answer!
