A circle with a radius of 3 meters is placed within a square. What is the area of the square minus the area of the circle?
Area of Circle = pi * radius^2 Area of Square = Length * Width or Length^2 Length = Diameter of Circle or 2*Radius Area of Square = 6*6 = 36 meters squared Area of Circle = pi * 9 = 28.27 meters squared Difference= Area of Square - Area of Circle = about 7.73 meters squared
