Question 360821
Hey,
So for this one, we need to find the area of the circle and subtract it from the area of the area of the square. First:
The area of a circle is (pi) times the radius squared. So: since the length of the square is 15, the radius of the circle is 7.5. The square of 7.5 is 56.25, that times (pi) which is 3.14 = 176.625. the area of the square is 15x15=225. Therefore:
225-176.625=  48.375 

I hope this helps!
