1.	6. The diameter and height of a cylindrical tank is 1.75 m and 3.2 m respectively.22How much is the capacity of tank in litre ? ( Ď =)
Answer» Solution : Dimensions of a cylindrical tank : Diameter ( d ) = 1.75 m = 175 cm radius ( r ) = d/2 = 175/2 cm Height ( h ) = 3.2 m h = 320 cm π = 22/7 Volume of the tank ( V ) = πr²h V = ( 22/7 ) × ( 175/2 )² × 320 V = 44000 cm³ V = 44 × ( 1000 cm³ ) V = 44 litres [ Since 1000 cm³ = 1 li ]

Answer»

Solution :

Dimensions of a cylindrical tank :

Diameter ( d ) = 1.75 m = 175 cm

radius ( r ) = d/2 = 175/2 cm

Height ( h ) = 3.2 m

h = 320 cm

π = 22/7

Volume of the tank ( V ) = πr²h

V = ( 22/7 ) × ( 175/2 )² × 320

V = 44000 cm³

V = 44 × ( 1000 cm³ )

V = 44 litres [ Since 1000 cm³ = 1 li ]
