Question

A shopkeeper has one laddoo of radius 5 cm. With the same material, how many laddoos of radius 2.5 cm can be made.

Answer 1

In the given problem, Let the number of smaller ladoos which can be made from a bigger ladoo be x.

Here,

The radius of the bigger ladoo (r₁) = 5 cm

The radius of the smaller ladoo (r₂) = 2.5 cm

So, according to the question, volume of the big ladoo is equal to the volume of x small ladoos.

Volume of the big ladoo = volume of the x small ladoos

Therefore, can be made from one ladoo of radius 5 cm.
