Question

A right triangle ABC with sides $7$cm, $24$cm and $25$cm is revolved about the side $24$cm. Find the volume of the solid so obtained.

Answer 1

When the Triangle is rotated the so obtained solid is cone

With height $24cm$ and radius $7cm$

Volume of cone is $\frac{1}{3}\pi r^{2}h\frac{1}{3}\times \frac{22}{7}\times 7\times 7\times 2456\times 22=1232c{m}^3$
