Question
Find the curved surface area of a right circular cylinder
whose radius is 14 cm and volume is 6,160 cm³. (Use π = 22/7)Solution
ATQ,
Volume of cylinder = π × radius² × height
So, (22/7) × 14² × height = 6,160
Or, (22/7) × 196 × height = 6,160
Or, 616 × height = 6,160
Or, height = 10 cm
Curved surface area of cylinder = 2 × π × radius × height
= 2 × (22/7) × 14 × 10
= 880 cm²
