For this case we have that by definition:
ρ[tex]= \frac {M} {V}[/tex]
Where:
ρ: It's the density
M: It's the mass
V: It's the volume
The volume of a cylinder is given by:
[tex]V = \pi * r ^ 2 * h[/tex]
Where:
A: It's the radio
h: It's the height
So:
[tex]V = \pi * 4 ^ 2 * 10\\V = 502.654824574366 \ cm ^ 3[/tex]
In addition, they tell us that:
ρ [tex]= 0.6 \frac {g} {cm ^ 3}[/tex]
We must clear the formula, the mass:
M = V * ρ
[tex]M = 502.654824574366 * 0.6\\M = 301.5929 \ g[/tex]
If we round, we have that the mass of the cylinder is given by:
301.59 grams
Answer:
301.59 grams
