Question

it costs Rs 2200 to paint the inner curved surface of a cylindrical vessel 10m deep. if the cost of Paint is at the rate of rs 20 per m^2 , find
(1) inner curved surface area of the vessel
(2) radius of the base
(3) capacity of the vessel

Answer 1

area = 2200/20 = 110
now, CSA of cylinder = 2πrh
110 m² = 2 X 22/7 X r X 10
110 m² = 440/7 X r
r = 110 X 7 / 440
r = 7/4
and volume

capacity of volume of vessel = πr²h
= 22/7 X 7/4 X 7/4 X 10
= 96.25 m²

hope it's help you
