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?
Percentage of area of circle=(area of circle/area of square)*100%
so,(pi(1)^2/2*2)*100% =78.54%
And 78.54% rounded to the nearest inetger = 79%
