How many m and ms are in a jar 7 inches diameter and 12 inches high?

To estimate the number of M&M's in a jar that is 7 inches in diameter and 12 inches high, first calculate the jar's volume using the formula for the volume of a cylinder: ( V = \pi r^2 h ). With a radius of 3.5 inches (half of the diameter) and a height of 12 inches, the volume is approximately 147.5 cubic inches. Given that an average M&M is about 0.5 cubic inches, you can estimate that the jar could hold around 295 M&M's, though this can vary based on packing efficiency and the actual size of the M&M's.
