Question

12. A water tank is formed with 5 points
the combination of cylinder
and hemisphere. The total
height of the tank is 24 m and
base area is 616 sq.m.If the
tank is filled with water at the
rate of 65 paisa per litre,what
is the total cost for the water ?
Find it.​

Answer 1

Answer:

Base area = 616m sq.

πr^2 = 616

r^2 = 616*7/22

r^2 = 196

r = 14

Radius =14 m

Height = 48 m

CSA of cylinder = 2πrh

=2*22/7*14*48

=5984m sq.

Volume of cylinder = πr^2h

=22/7*14*14*48

=29568m cube
