Given :
To find :
Solution :
Volume of bigger cylinder = πR²H cu. unit
= π × (4)²× 7 cm³
= (π × 16 × 7) cm³
Volume of smaller cylinder = πr²h cu. unit
= π × (2)²× 3/2 cm³
= (π × 4 × 3 1/2) cm³
[We can find the number of smaller cylinders to be made by melting the bigger cylinder by dividing the volume of bigger cylinder by the volume of smaller cylinder.]
Hence, the number of smaller cylinders that can be made is 8.
