The radius of the can is
Explanation:
The formula for volume of a cylinder is:
Since we know the volume and the height of the can, we can determine the radius.
Cancelling the similar terms on either side, we get.
Divide both sides by
Square both sides, remembering that the result has to be a positive integer.
Hence the radius of the cylindrical can is
