Question
The curved surface area of a cylindrical pipe is 990 cm².
If the height of the pipe is 15 cm, then find the diameter of the pipe.Solution
ATQ,
Let the radius of the pipe be 'r' cm.
Curved surface area of the cylinder = 2 × π × radius × height
ATQ,
2 × (22/7) × 15 × r = 990
So, r = (990 × 7) ÷ (2 × 22 × 15) = 10.5
Therefore, diameter of the pipe = 2 × r = 2 × 10.5 = 21 cm
