A vessel is in the form of a hemispherical bowl surmounted by a hollow cylinder of same diameter.The diameter of the hemispherical bowl is 14cm and the total heigh of the vessel is 13cm.find the total surface area of the vessel.


the diameter of the hemispherical bowl = 14 cm

the radius of the hemisphere r = 14/2 = 7cm
the curved surface area of the bowl =
the total height of the vessel = 13 cm

the height of the cylindrical part = 13-7= 6 cm
the surface area of the cylinder =
total surface area of the vessel = surface area of the cylinder + surface area of the sphere

=308+264

=572 sq cm
