Question

49. How much water will be contained in a cylindrical cement tank, if the diameter of the tank is 7m and height is 6 times the radius? (1) 808500 litres (2) 880500 litres (3) 850800 litres (4) 800500 litres​

Answer 1

Answer:

Step-by-step explanation:Capacity of Tank = 808.5 cubic meters

Step-by-step explanation:

The tank is in cylindrical shape.

Hence capacity of tank = volume of cylinder = πr²h

r - radius of the base

h - height of the cylinder.

Given that

Diameter of the cylinder = 7 m

Radius = r = Diameter / 2 = 7 / 2 = 3.5 m

Height = 6 times the radius = 6r = 6 * 3.5 = 21 m

Capacity of Tank = πr²h

Substituting above values we get

Volume (or Capacity of tank) = 22*3.5*3.5*21/7 = 22*3.5*3.5*3

= 808.5 cubic meters or 808500 litres so option a is correct
