Question

From a solid right circular cylinder with height 10 cm and radius of the base 6 cm, a right circular cone of the same height and base is removed.Find the volume of the remaining solid.$(Take\pi =\mathrm{3.14.})$

Answer 1

Remaining volume of solid=volume of cylinder-volume of cone
=3.14(r x r)(h)-(3.14)(r x r)(h/3)
=(3.14)(r x r) (h-h/3)
=(2/3)(3.14)(r x r)h
=(2/3) x (22/7) x 6 x 6 x 10
=$753.6c{m}^3$
