A vessel is in the form of a hollow cylinder mounted on a hollow hemisphere. the diameter of the hemisphere is 14cm, and the total height vessel is 3cm. find the outer surface area of the vessel?
Read Solution (Total 3)
-
- surface area of hemisphere part= 2*(pi)*d^2/4=308
surface area of cylindrical part= 2*(pi)*r*h=132
thus total SA=440 cm2 - 14 years agoHelpfull: Yes(9) No(6)
- surface area of cylinder=2*(22/7)*r*h=132
surface area of hemisphere=2(22/7)*r*r
surface area of vessel=sum of both - 14 years agoHelpfull: Yes(4) No(4)
- outer surface area of vessel=2*pi*r*h=132 is the nans
- 14 years agoHelpfull: Yes(1) No(2)
