Answer 1

A1) The volume of the cylinder is

V = ?h(d/2)²

where h = average height of the cylinder and d = average diameter of the cylinder. Plug in values and get

V = 3.14*(2.14 cm)*(1.27 cm/2)² = 3.14*(2.14 cm)*(0.635 cm)² = 2.70951 cm³.

The density of the cylinder is

d = M/V

where M = average mass of the cylinder. Plug in values and get

d = (20.76 g)/(2.70951 cm³) = 7.6619 g/cm³ ? 7.66 g/cm³ (ans).

A2) We know that

1 ounce = 28.3495 g.

1 inch = 2.54 cm.

Therefore, (1 inch)³ = 1 inch³ = (2.54 cm)³ = 16.38706 cm³.

The density of the cylinder is 7.66 g/cm³.

The volume of the cylinder is given as

V = M/d

Plug in values and obtain

V = (29.2 ounce)*(28.3495 g/1 ounce)/(7.66 gcm³) = 108.06895 cm³ = (108.06895 cm³)*(1 in³/16.38706 cm³) = 6.594773 in³ ? 6.59 in³ (ans).
