The volume of steel needed to manufacture the 55cm pipe is
11,052.80 cm³
Given:
length or height = 55 cm long
inner radius = 8 cm
outer radius = 10 cm
volume of pipe = ?
Pipe volume is computed by multiplying pi with radius raised to the 2nd power and by the height of the pipe.
Pipe volume = π r² h
let π = 3.14
radius used is the inner radius of the tube = 8cm
Pipe volume = 3.14 * (8cm)² * 55cm
Pipe volume = 3.14 * 64 cm²* 55 cm
Pipe volume = 11,052.80 cm³
