A shopkeeper has one laddoo of radius 5 cm. With the same material, how many laddoos of radius 2.5 cm can be made.
Volume of a sphere = (4/3)πr3
Given, shopkeeper has one laddoo of radius 5 cm
Volume of the laddoo = (4/3) × (22/7) × 53
Now, from this one laddoo, laddoos of radius 2.5 cm are to be made.
Volume of laddoo of radius 2.5cm = (4/3) × (22/7) × 2.53
∴ No. of laddoos of radius 2.5 cm that can be made
