The capacity of a cylindrical tank is 246.4 litres.
The capacity of a cylindrical tank is 246.4 litres. If the height is 4 metres, what is the diameter of the base?
Answer/Solution
none of these
Steps/Work
Capacity (volume) of a cylindrical tank = πr2h
(Here r = radius and h = height of the tank)
Now, from the question, 246.4 × 0.001 = 22⁄7 × r2 × 4
[∵ 1 litre = 1000 cm3 = 0.001 m3]
or, 0.2464×7/22×4 = r2
or,r = 0.14 m
or,diameter = 2r = 0.28 m
Answer E
(Here r = radius and h = height of the tank)
