From a cylindrical milk tanker of radius 1.5 m and length 7 m how many

1.	From a cylindrical milk tanker of radius 1.5 m and length 7 m how many polythene of one liter can be packed? (1 m3 = 1000 liter).
Answer» For tanker Radius (r) = 1.5 meter Height (h) = 7 meter ∴ Volume = πr²h = 22/7 . (1.5) (1.5) x 7 = 49.5 m³ = 49.5 x 1000 litre = 49500 litre Hence, the required number of polythene packs are 49500.

Answer»

For tanker

Radius (r) = 1.5 meter

Height (h) = 7 meter

∴ Volume = πr²h

= 22/7 . (1.5) (1.5) x 7

= 49.5 m³

= 49.5 x 1000 litre

= 49500 litre

Hence, the required number of polythene packs are 49500.
