21.  The diagram shows a circle of radius 1 contained in a square. If the area of the circle equals x% of the area of the square, then what is x rounded to the nearest integer?

Area of square  with a side of 2r  = 2(1)  = 2  = 2^2   = 4

 

Area of circle =  pi ( 1)^2  =  pi

 

x =  pi / 4   ≈  .79   =  79%
