Answer:
a). Volume = 62.86 cm³
b). Density of the cork = 0.03977 gms per cm³
Step-by-step explanation:
A cork in the shape of a cylinder has the radius 'r' = 2 cm
and height of the cork = 5 cm
a). Formula for the volume of the cork = [tex]\pi r^{2} h[/tex]
Where r = radius of the cork
h = height of the cork
V = [tex]\pi (2)^{2}(5)[/tex]
= 20π
= 62.86 cm³
Therefore, volume of the cork is 62.86 cm³.
b). Formula for cork's density = [tex]\frac{\text{Mass}}{\text{Volume}}[/tex]
= [tex]\frac{2.5}{62.86}[/tex]
Therefor, Density of the cork = 0.03977 grams per cm³
