A sumo wrestling ring is circular and has a circumference of 4.6\pi \text{ meters}4.6? meters. What is the area AA of the sumo wrestling ring in square meters? Give your answer in terms of \pi?. A=A= \text{m}^2m 2

Respuesta :

Answer:

The area is equal to [tex]5.29 \pi\ m^{2}[/tex]

Step-by-step explanation:

Step 1

Find the radius r

we know that

the circumference of a circle is equal to

[tex]C=2\pi r[/tex]

In this problem we have

[tex]C=4.6 \pi\ m[/tex]

Substitute in the formula and solve for r

[tex]4.6 \pi=2\pi r[/tex]

[tex]r=4.6/2=2.3\ m[/tex]

Step 2

Find the area

we know that

The area of a circle is equal to

[tex]A=\pi r^{2}[/tex]

substitute the value of r

[tex]A=\pi (2.3^{2})=5.29 \pi\ m^{2}[/tex]
