Question
Calculate the difference between the area of a wall
having dimension 22 cm X 23 cm and the area of a spherical bowl having diameter 14cm.Solution
Area of the wall = 22 X 23 = 506 cm2Area of the spherical bowl = 4 X π X r2Here, radius of the spherical bowl = Diameter/2Radius of the spherical bowl = (14/2) = 7 cmArea of the spherical bowl = 4 X (22/7) X 7 X 7 = 616 cm2Required difference = 616 - 506 = 110 cm2
