Answer 1

What fraction of the area of the square is the area of the circle?

 

Let r = radius of the circle. Then the side of the square is 2r.

 

Area of square = (2r)(2r) = 4r².

 

Area of circle is πr².

 

So the answer to the first question is πr²/4r² = π/4. Find the decimal equivalent and convert to a percentage.
