A sumo wrestling ring is circular and has a circumference of 4.6pi meters
What is the area A of the sumo wrestling ring in square meters?
Give your answer in terms of \piπpi.

Answer 1

Answer:

5.29π m²

Step-by-step explanation:

C = 2πr = 4.6π ( divide both sides by 2π )

r = $\frac{4.6\pi }{2\pi }$ = 2.3, thus

A = πr² = π × 2.3² = 5.29π m²
