Question

A skater skates 8.23 meters from the edge to the center of a circular skating rink. What is the area of the rink?

Answer 1

Given:-

• A skater skates 8.23 meters from the edge to the center of a circular skating rink.

To Find:-

• The area of the rink

Formula Used:-

• ${\boxed{\bf{Area\:of\:Circle=\pi r^2}}}$

Solution:-

From the information given, we get to know that the radius of the circular rink is 8.23 m. So,

$\sf :\implies\: Area\:of\:Rink=\pi r^2$

$\sf :\implies\: Area\:of\:Rink=3.14\times 8.23^2$

$\sf :\implies\: Area\:of\:Rink=3.14\times 67.7329$

${\boxed{\bf{:\implies\: Area\:of\:Rink=212.681306\:cm^2}}}$

Hence, The Area of the Circular Skating rink is 212.68 cm².
