A cylinder made of lead has a height of 4 inches and a diameter of 2 inches. How heavy is the cylinder if lead weighs 0.4 pound

My name is Ann [436]

Answer:5.0

Step-by-step explanation:

The volume of a cylinder is $\pi r^2h$ , since the radius is 1/2D, 2/2=1. Now, if $\pi$ is rounded to 3.14, the volume of the cylinder would be 1 x 1 x 3.14 x 4 = 12.56. Now, since there are 0.4 pound per cubic inch, 12.56 x 0.4 = 5.024. Rounded to tenth, the answer is 5.0 or 5.
