The density can be found with the formula, density equals mass over volume (d = m/v):
The mass is given m = 540 grams, you can plug that into the formula first.
The volume v can be found with the formula for Volume of a Cylinder (because it's rod-shaped):
V = πr2h
H is the height or length, R is the radius or half of the diameter, and π can remain or it can be rounded to 3.14.
Assuming the length is in centimeters (you didn't put the unit of measurement so I'm not sure), you can plug in h = 38 and r = 1.25 to find the volume. Then put the volume into the density formula to solve. Your answer's unit will be "grams per cubic centimeter."
