Question

The circumference of a boxing ring is 37.68 yd. What is the APPROXIMATE area of the boxing ring? Use 3.14 for π.

1. 904.4 sq yd
2. 113.0 sq yd
3. 452.2 sq yd
4. 226.1 sq yd

Answer 1

2. 113.0 yd²

Explanation:

Circumference Formula: C = 2πr

Area of a Circle Formula: A = πr²

Since we are given circumference, simply plug it in to find radius r:

Step 1: Find r

37.68 = 2πr

r = 37.68/2π

r = 5.99696

Step 2: Find area

A = π(5.99696)²

A = 112.983
