A music store offers a prize to a customer who can guess the closest, the number of jelly beans that fill a litre jar on the counter. Estimate the number of jelly beans in the jar if 1 jelly bean is approximately 2 cm long (h) by 1.5 cm in diameter (d).
Volume = h x π x (d/2)2 (if you donít have π on your calculator, use 3.1416 instead)
NB: 1 litre = 1000 cm3,
2cm x 3.1416 x (d/2)2 = 3.53 jelly beans
