Q5 of 32 Page 260

In the adjacent figure, the height of a solid cylinder is 10 cm and diameter is 7 cm. Two equal conical holes of radius 3 cm and height 4 cm are cut off as shown the figure. Find the volume of the remaining solid.

Given that, height of cylinder is 10 cm and diameter is 7 cm.Also, radius of cone is 3 cm and height is 4 cm.


⇒ radius of cylinder


⇒ the volume of the remaining solid = vol. of cylinder-2(vol.


Of cone)





= 309.57 cm3
