A vessel is in th

Answer :

Given-

Diameter of Hemispherical bowl = 14 cm


Radius of Hemispherical Bowl(r) = Radius of Cylinder(r)


= 7 cm


Total Height of Vessel = 13 cm


Height of Cylinder(h) = 13-7 = 6 cm


Curved Surface Area of Cylinder = 2× π × r× h


= 2× (22/7) × 7× 6


= 264 sq. cm


Curved Surface Area of Hemispherical Bowl = 2 × π × (r)2


= 2× (22/7) × (7)2


= 308 sq. cm


Thus, total (inner) surface area of the vessel = 264+308


= 572 sq. cm
