The side of a square metal sheet is 7 m. A circu-lar sheet of maximum radius is cut out of it andremoved. Find the area of the circular sheet (in ft^2)

Answer»

Diameter of largest circle that can be cut is 7cm. (see picture)So radius = 7/2 = 3.5m

Area of circular part is πr^2=22/7*3.5*3.5=22*0.5*3.5=38.5m^2
