Answer 1

Question : The tank of petrol lorry is a cylinder 2m in diameter and 7m long calculate it's capacity in kilometer.

Solution : Shape of tank is cylindrical

Now, diameter of tank is 2m and length of tank is 7m

⟹ Diameter of tank = 2m =

⟹ Radius of tank, r = 1m

⟹ Length (height) of tank, h = 7m

To find holding capacity of tank we use formula of volume of cylinder.

⟹ Volume of tank = πr²h

⟹ Volume of tank = 22/7 * ( 1 )² * 7

⟹ Volume of tank = 22/7 * 1 * 7

⟹ Volume of tank = 22 m³

Now to find capacity of tank in km.

⟹ Volume of tank = 22 * (1000)³ km³

⟹ Volume of tank = 2.2 * 10¹⁰ km³

Answer : Hence, capacity of tank is 2.2 * 10¹⁰ km³.
