    Step-by-step explanation:

    Radius of laddoo=5cm

    Volume of laddo=4/3×pi (radius)^3 cc=4/3×pi×5^3cc

    Radius of smaller laddoo=2.5cm

    Volume of each small laddoo=4/3×pi 2.5^3cc

    Let n small laddoos be made from the large laddo.

    Therefore 4/3×pi×5^3=4/3×pi×2.5^3×n

    => 5^3=n×2.5^3

    => n =( 5/2.5)^3=2^3=8

    8 laddoos of radius 2.5cm can be made from 1 laddoo of radius 5cm.
