From a square metal sheet of side 28 cm, a circular sheet is cut off. Find the radius of the largest possible circular sheet that can be cut. Also, find the area of the remaining sheet.
For largest circle to be inscribed in a square;
side of square = diameter of circle
28 = 2 × radius
radius = 14 cm
So, area of circle = π radius2
= 44 × 14
= 616cm2
