The Total solution for NCERT class 6-12
Given,
Diameter of thehemisphere = 14 cm
So, the radius of thehemisphere = 7 cm
Total height of thevessel = 13 cm = h + r
Now,
Inner surface area ofthe vessel = 2 π r (h + r)
= 2 (22/7)(7)(13)
= 572 cm2
Therefore, the innersurface area of the vessel is 572 cm2
