Question

A cricket trophy cup is in the shape of a solid cylinder whose base diameter is 14 cm and height 15 cm. A cricket ball of diameter 7 cm is surmounted on it. The total cup is fixed on a cuboid of dimensions 14 cm × 14 cm × 7 cm. Find the volume of the trophy along with the base .

Answer 1

cylinder :  base radius = 14/2 = 7 cm ,  height = 15 cm
        volume = 22/7 * 7² * 15 = 22 * 105 cm³ = 2310 cm³
spherical ball:  radius = 7/2 = 3.5 cm
        Volume = 4/3 * 22/7 * 3.5³ = 11*49/3  cm³ = 179.67 cm³
cuboid:   14cm X 14cm X 7 cm 
    volume = 196* 7 cm³ = 1372 cm³

Total volume of the trophy = 3, 861.67 cm³   (adding the three solids)
