A vessel is in the form of a hollow hemisphere mounted by a hollow cylinder. The diameter of the hemisphere is 14 cm and the total height of the vessel is 13 cm. Find the inner surface area of the vessel.

Text Solution

Verified by Experts

Inner surface area ofvessel=`4pir^2+2pirh`
here r=7cm and h=6cm
subtituting values=>`4xx22/7xx49+2xx22/7xx7xx6`
=>`880(cm)^2`
