Question
A hollow cylindrical pipe has an inner radius of 8 cm. If
the length of the pipe and the thickness of the pipe are 12 cm and 2 cm, respectively, determine the approximate volume of the pipe. (Use π = 22/7)Solution
ATQ,
Outer radius of the pipe = 8 + 2 = 10 cm
Volume of the pipe = π × height × [(outer radius)² - (inner radius)²]
= (22/7) × 12 × (10² - 8²)
= (22/7) × 12 × (100 - 64)
= (22/7) × 12 × 36
= 1,123.71 cm³ or 1124 cm³
