Dear Sunils1610@gmail.com

There appears to be a mismatch in the information provided, the question asked in the end of this question ('height of the cone is')
and the options provided along with this question (which has no link with the height).
Kindly look into the question again and rectify the fault.

Regards

Topperlearning Team.
