Acylindrical piece of aluminium is 6.00 cm tall and 2.00 cm in radius. how much does it weight

2.00 N

Explanation:

The weight is the mass times gravity:

W = mg

The mass is the density times volume:

m = ρV

The volume of a cylinder is:

V = πr²h

Therefore:

W = π r² h ρ g

Given r = 2.00 cm, h = 6.00 cm, ρ = 2.70 g/cm³, and g = 9.8 m/s²:

W = π (2.00 cm)² (6.00 cm) (2.70 g/cm³) (1 kg / 1000 g) (9.8 m/s²)

W = 2.00 N
