You can put this solution on YOUR website! How do you find the area of a circle with a square (with side length of 2) inside of it?
Draw the picture and label the sides of the square.
-------------------------
Use Pythagoras: diagonal = sqrt(2^2+2^2)=sqrt8 = 2sqrt2
So, the diagonal of the square is 2sqrt2.
--------------------
That diagonal is the diameter of the circle.
The area of the circle is pi* r^2.
Area = pi* [(2sqrt2)/2]^2
Area = pi*2
Area of the circle is 2pi
