Question

5. 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

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
