Question

What is the mass of a cylinder of lead that is 1.80 in in diameter, and 4.12 in long. the density of lead is 11.4 g/ml?

Answer 1

Answer:The mass of the lead cylinder is 1,995.898 g.

Explanation:

Radius of the cylinder,r =$\frac{Diameter}{2}=\frac{1.80 inches}{2}=0.9 inches$

Height of the cylinder,h = 4.12 inches

Volume of the cylinder: $\pi r^2h=3.14\times (0.9 inches)^2\times 4.12 inches=10.47 inches^3$

$inches^3=16.3871 ml$

Volume of the cylinder in ml= $10.47\times 16.3871 ml=171.57 ml$

Density of the lead cylinder = 11.4 g/ml

$density=\frac{Mass}{Volume}$

$Mass=11.4 g/ml\times 171.57 ml=1,955.898 g$

The mass of the lead cylinder is 1,995.898 g.

Answer 2

1950 g This is the answer due to the kilograms of lead being distributed
