Question

The diameter and height of a cylindrical tank is 1.75 m and 3.2 m respectively. How much is the capacity of tank in litre? [π = 22/7]

Answer 1

Given: For cylindrical tank: diameter (d) = 1.75 m, height (h) = 3.2 m

To Find: Capacity of tank in litre 

diameter (d) = 1.75 m = 1.75 x 100 ….[∵ 1 m = 100cm] 

= 175 cm 

∴ radius (r) = d/2 = 175/2 cm 

h = 3.2 cm 

= 3.2 x 100 

= 320 cm 

Capacity of tank = Volume of the cylindrical tank = πr²h

∴ The capacity of the tank is 7700 litre.
