Apark has a large circle painted in the middle of the playground area. the circle is divided into 4 equal sections, and each section is painted a different color. the radius of the circle is 10 meters. what is the area a of each section of the circle? give your answer in terms of pi.

First you need to find the area of the whole circle.
The radius is given as 10, so just insert 10 into the equation of the area of a circle equation. 

Putting  after the 100 because that is what is commonly done. 

Because the circle is then being split into 4 equal sections, we need to find 1/4 of the area of the whole circle to find the area of one of these sections. 

Since the area of the whole circle is  then we just divide that by 4, 
leaving us with 25 and that is our final answer
