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 = 1 unit^2
The circle has a radius of (1/2)
So...its area is : pi (1/2)^2 = pi / 4 units^2
So area of circle to area of square = [ pi / 4] : 1 = pi / 4 ≈ .785 ≈ 79%
thx your the best
