Q10 of 44 Page 14

From a circular cylinder of base diameter 10cm and height 12cm, a conical cavity with the same base and height is carved out. Find the volume of the remaining solid.

Given that Diameter of circular cylinder = 10cm

∴ Radius of the cylinder


and Height of the cylinder = 12cm


So,


Volume of the cylinder = πr2h



= 942.857 cm3




= 314.285 cm3


Remaining Volume = Volume of the cylinder – Volume of cone


= 942.857 – 314.285


= 628.572 cm3

A student was asked to make a model in his workshop, which shaped like a cylinder with two cones attached at its two ends, using a thin aluminium sheet. The diameter of the model is 3 cm and its length is 10 cm. If each cone has a height of 2cm, find the volume of air contained in the model. (Consider the outer and inner dimensions of the model to be nearly the same).
