Answer:
100π cm³
Step-by-step explanation:
When right-angled ΔABC is revolved about its side 12 cm, a cone with height (h) as 12 cm, radius (r) as 5 cm, and slant height (l) 13 cm will be formed.
radius r = 5 cm
height h = 12 cm
and slant height l = 13cm
Now, volume of the cone = πr2 h/3
= {π 52 * 12}/3
= {π *5 * 5 * 12}/3
= π *25 * 4
= 100π
Therefore, the volume of the cone so formed is 100π cm³

Answer:
Step-by-step explanation:
Volume of triangle = 1/2 x l x b x h
1/2 x 5 x 12 x 13
= 390 cm³
