Question

A vessel is in the form of a hollow hemisphere mounted by a hollow cylinder. The diameter of the hemisphere is 14cm and the total height of the vessel is 13cm. find the inner surface area of the vessel.

Answer 1

total surface area of vessel=curved surface area of hemisphere+curved surface area of cylinder

= 2πr square +2πrh
=2.22/7.7.7+ 2. 22/7. 7. 6
=44/7 + 44.6
iske a age fraction me lekr solve kr Lena . yahaan possible ni he solve kr na

Answer 2

Answer : 572cm2

Step-by-step explanation:

Diameter = 14cm

Radius=14/2

=7cm.

Height of the cylinder= 13-7

= 6cm

Now,inner surface area of the vessel=csa of cylinder +csa of hemisphere

2(pie)rh+2(pie)r^2h

84(pie)+98(pie)

182(pie)

182.22/7

26.22

572 cm^2..............
