2. A vessel 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 vessel.​

Answer 1

Answer:

Hey Before Checking the answer remember [ I Put ( ^ ) this as represented as power of number]

Step-by-step explanation:

According to the question,

Radius (r) of the cylindrical part = 7cm

And

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 + 2 πr^2

Inner surface area of vessel = (2×22/7× 7 × 6) + (2×22/7× 7) = (44 × 6) + ( 44 × 7)

= 44 (6 + 7)

= 44 × 13

= 572 cm^2
