Question

A right angle triangle abc with sides 5cm ,12cm ,13cm is revolving about 12cm .find the volume of solid obtained

Answer 1

The volume of cone generated due to rotation is given by
$v = \frac{\pi {r}^{2}h }{3}$
where r=5, h=12
hence v=315.15 cubic cm

Answer 2

Answer:

the figure is like that..

volume of the solid = 1/3πr^{2}h

1/3 ×π ×25×12

100π^{3}
