How many spheres 12 cm in diameter can be made from a metallic cylinder of diameter 8 cm and height 90 cm?

Given,


Diameter of cylinder = 8cm


Radius = 4cm


Height = 90cm


Diameter of sphere = 12cm


Radius = 6cm


When we convert any object into another shape the volume will remain same.


Volume of cylinder = n × volume of sphere






n = 5
