Answer 1

Answer:

572 cm^2

Step-by-step explanation:

Diameter of hemispherical part = 14 cm.

Radius(r) of the hemispherical part = 7 cm

Height of hemispherical part = Radius = 7 cm

Height of cylindrical part (h) = 13 - 7 = 6 cm

Now,

Inner surface area of the vessel = CSA of cylindrical part + CSA of hemispherical part.

=> 2πrh + 2πr^2

=>  2 * 22/7 * 7 * 6 + 2 * 22/7 * 7 * 7

=> 264 + 308

=> 572 cm^2.

Therefore, Surface area of the vessel  = 572 cm^2

Hope it helps!
