Question

15. An oil can is in the form of cylinder
whose radius is 7.7 cm and length is
56 cm. Find the quantity of oil in litres
that can be stored in the can?
​

Answer 1

Quantity of oil stored in can=volume

of can = pir2h

2217x7.7x7.7x56

10435.04cm

1L=1000cm

Answer 2

Volume of Cylinder = πr²h

⇒ Volume of Cylinder = π × r² × h

⇒ Volume of Cylinder = 22/7 × r² × h

⇒ Volume of Cylinder = 22/7 × (7.7 cm)² × h

⇒ Volume of Cylinder = 22/7 × (7.7 cm)² × 56 cm

⇒ Volume of Cylinder = 22/7 × 59.29 cm² × 56 cm

⇒ Volume of Cylinder = 22/7 × 59.29 × 56 cm³

⇒ Volume of Cylinder = 10435.04 cm³

⇒ Volume of Cylinder = 10435.04 ml

⇒ Volume of Cylinder = 10.43504 L
