Question
A metal cylinder has a curved surface area of 528 cm² and
its height is 12 cm. What is the diameter of the cylinder?Solution
ATQ,
Let the radius of the cylinder be 'r' cm.
Curved surface area of the cylinder = 2 × π × radius × height
ATQ,
2 × (22/7) × 12 × r = 528
So, r = (528 × 7) ÷ (2 × 22 × 12) = 7
Therefore, diameter of the cylinder = 2 × r = 2 × 7 = 14 cm
