A circular tray of radius 21 cm has a circular plate of radius 14 cm placed at its centre. Find the area of the tray that is NOT covered by the plate. (Take π = 22/7)

Question

Accepted Answer

770 cm^2. Tray = 22/7*21*21 = 1386 cm^2. Plate = 22/7*14*14 = 616 cm^2. Uncovered = 1386 - 616 = 770 cm^2.
