Suppose you are given a square with an inscribed circle. if the area of the square is 36 m^2. what is the area of the circle?

Area of a square is a^2. So that means one side of a square is equal to 6 m. 
So that would be the diameter of the circle. And the area of a circle is pi(r^2), where r represents the radius. 

So plug in the equation. pi(3^2). This will get you 28.3 - rounded to the nearest tenth.
