  1. 2258.7 cm

    Step-by-step explanation:

    Given = radius of cone, cylinder, hemisphere = 7 cm

    the hight of cone, cylinder = 4 cm

    Now the volume of cone = 1/3πr^2h

    = 1/3 * 22/7 * 7 * 7 * 4

    = 1/3 * 22 * 7 * 4

    = 616/3

    Now the volume of cylinder = πr^2h

    = 22/7 * 7 * 7 * 4

    = 22 * 7 * 4

    = 616

    Now the volume of hemisphere = 4/3πr^3

    = 4/3 * 22/7 * 7 * 7 * 7

    = 4/3 * 22 * 7 * 7

    = 4312/3

    Now, according to the question, they all are joined from their end points

    = 616/3 + 616 + 4312/3

    = 616 + 1848 + 4312/3

    = 6776/3

    = 2258.7 cm
