A plastic pipe 10 cm long has an outside diameter of 5 cm and an inside diameter of 4 cm. If the density of the plastic is 0.92 g/cm3, what is the mass of the pipe? Use 3.14 for π, and round your answer to the nearest gram

Mass of the pipe = 65 gram (Approx)

Step-by-step explanation:

Given:

Length of pipe (h) = 10 cm

Outer diameter = 5 cm = r1 = 5 / 2 = 2.5

Inner diameter = 4 cm = r2 = 4 / 2 = 2

Density of the plastic = 0.92 g/cm³

π = 3.14

Find:

Mass of the pipe = ?

Computation:

Mass of the pipe = 70.65 × 0.92 g/cm³

Mass of the pipe = 64.998 gram

Mass of the pipe = 65 gram (Approx)
