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

Answer :

Given that, radius of a spherical laddoo = 5 cm

Volume of that laddoo, v = 4/3 πr^{3}

⇒

We have 523.81 cm^{3} of material of laddoo.

Volume of laddoo of radius 2.5 cm =

Then, laddoos that can be made out of 523.81 cm^{3} volume of laddoo material, of radius 2.5 cm can be found out as,

No. of laddoos = 523.81/65.48 = 8

**Thus, 8 laddoos of radius 2.5 cm can be made out of the same amount of material.**
