Question

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.
of radins 35 cm mounted on a hemisphere of same radius​

Answer 1

Step-by-step explanation:

ANSWER

Given:

Radius of hemisphere and cylinder is r=7 cm

Height of cylinder is h=13 cm

Surface area of hemisphere of radius r is given by S

1

=2πr

2

Surface area of curved surface of a cylinder of radius r and height h is S

2

=2πrh

Total surface area is S=2πr

2

+2πrh

S=2π×7

2

+2π×7×13

S=280π cm
