Given,
In cylinder,
radius=10cm, height=21cm
In cone,
radius=10cm, height=h
πr^2h-(1/3)πr^2h=4400
(22/7)*100*21-(1/3)*(22/7)*100*h=4400
On solving you get,
h=21cm.

Answer:
Correct option is C)
Step-by-step explanation:
Let the height of cone be 'h', then
πr
2H= 31 πr2h=4400㎤
⇒πr 2[21− 3h]=4400⇒63−h=
22×10×10
3×4400×7 =42
⇒h=63−42= 21㎝.
