Calculate 47933

Calculate the weight of the steel roller if d = 2.4 cm, height v = 5.6 cm, density ρ = 8 g / cm3.

Correct answer:

m =  202.6704 g

Step-by-step explanation:

d=2.4 cm v=5.6 cm ρ=8 g/cm3  r=d/2=2.4/2=56​=1.2 cm V=π⋅ r2⋅ v=3.1416⋅ 1.22⋅ 5.6≐25.3338 cm3  m=ρ⋅ V=8⋅ 25.3338=202.6704 g
