You just need to find a rough estimate of the volume of the jar and the volume of one jelly bean. This is called magnitude order.
The <em>jellybean ja</em>r is cylindrical, Thus, its volume is
To find the order of magnitude, you just use the numbers rounded to one signficant figure: round π to 3, the radius to 5, cm, and the height to 10:
The order of magnitude for the radius of a jellybean is 1 cm. And the order of magnitude of the volume of a sphere with a radius of 1 cm is the cube of the diameter (2cm):
Hence, a reasonable lower limit for the number of jellybeans in the jar is:
