Answer:
= 1144 cm2
Step-by-step explanation:
Let the radius and height of cylinder be r cm and h cm respectively.
Diameter of the hemispherical bowl = 14 cm
Radius of the hemispherical bowl = Radius of the cylinder = r
Total height of the vessel = 13 cm
Height of the cylinder, h = 13 cm - 7 cm = 6 cm
Total surface area of the vessel = 2 (curved surface area of the cylinder + curved surface area of the hemisphere)
(Since, the vessel is hollow)
= 1144 cm2
