How Do You Guess The Amount Of Jelly Beans In A Jar?
As the word “guess” implies, there’s no foolproof method to guess the amount of jelly beans in a jar. Generally it seems that the prize in such contests goes not to anyone with a strategy, but to someone who just pulled a number out of thin air. However, there is a mathematical method that should get you at least into the ballpark of the actual number of jelly beans in a jar. Count the number of jelly beans around the outside of the bottom of the jar. Start with a bean that sticks out from the ones around it, or put your finger somewhere to keep track. Try to count the number of beans in just a single layer, as accurately as you are able. This number can be considered to be the circumference of the jar, measured in bean units. Use the formula for finding a circle’s circumference to find the circle’s radius in bean units. This formula is circumference = 2 x pi (approximately 3.14) times the radius. By rounding pi off slightly more, we can approximate the formula as circumference = radiu
