A cylinder rod formed from silicon is 46.0 cm long it has a mass of 3.00 kg. The density of silicon is 2.33 g centimeters cubed. What is the diameter of the cylinder?

Explanation:

First find the volume from the density.

d = mass/volume

mass = 3.00 kg = 3000 grams

density = 2.33 g/cm^3

volume = mass/ density

volume = 3000 / 2.33

volume = 1287.6 cm^3

Next use the volume to find the radius.

V = pi * r^2 * h

V = 3.14 * r^2 * 46

1287.6 /46 = 27.99

27.99 / 3.14 = 8.91

r^2 = 8.91

r = 2.99

2r = d = 5.97
