Question

A large battery is a cylinder with the dimensions shown below. What is the total weight, rounded to the nearest gram, if the density of the battery is

Answer 1

All I can tell you is that g=32.2f/s^2; or 9.81m/s^2.

Answer 2

Mass (weight) = density × volume

You are given the density (12 g/cm³). The volume of a cylinder is:

Volume = π·r²·h

where r is the radius of the top and bottom and h is the height of the cylinder. Plug in the numbers and compute the volume. Then use the first formula to find the weight.
