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
