Answer» l 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 vassel.Given :-The diameter of the hemisphere is 14 cm. Total height of the vessel is 13 cm.To find :-The inner surface area of the vessel.We Know :-➢Diameter of the hemisphere = 14 cm➢Radius of the hemisphere will be ➢Height of the hemisphere = Radius of the hemisphere = 7 cm➢So, the radius of the cylinder will be 7 cm➢Height of the cylinder = Height of the vessel – Height of the hemisphere ➢Height of the cylinder = 13 - 7 = 6 cm➢➢➢➢∴ The inner surface area of the vassel = C.S.A. of CYLINDRICAL PORTION + C.S.A. of hemispherical portion➢308 + 264Identities used!!!More Identities...!!
