Answer: the density of the cylinder is 19.3 grams per cubic centimeter.
Step-by-step explanation:
First, calculate the volume of the cylinder using the formula V = πr^2h, where V is the volume, r is the radius of the base, and h is the height.
If the base radius is 3, then the radius is equal to 3 cm. Therefore,
V = π(3 cm)^2 (5 cm) = 141.37 cm^3.
Next, if you want to calculate the density of the cylinder, you need to divide the mass of the cylinder (2729.916 grams) by its volume (141.37 cm^3), which will give you the density in units of grams per cubic centimeter (g/cm^3).
Density = mass / volume = 2729.916 g / 141.37 cm^3 = 19.3 g/cm^3 (rounded to one decimal place).
Therefore, the density of the cylinder is 19.3 grams per cubic centimeter.
