Answer:
750g of Aluminum
Assuming 8.6 cm lenth is the height of the cylinder. The volume of a cylinder is: V = 
*r^2*h
V = 3.14cm x 10.24cm x 3.6cm
V = 280cm^3
Now density = mass/volume
2.7g/cm^3 = mass/280cm^3
2.7g/cm^3 x 280cm^3 = mass/<u>280cm^3</u> x <u>280cm^3</u>
= 750g of Aluminum

Hope it helps, some how.
Answer:
The correct answer is option (1).
Explanation:
Mass of the sample = 5.5 g
Percentage of carbon in sample = 35 %
Percentage of oxygen in sample = 100% - 35%
Mass of carbon in a sample: (35%) of 5.5 g
Mass of oxygen in a sample: (100%-35%) of 5.5 g
