Next, you can determine how many inches there are in 5 3/4 inch (14.605 cm) circumference by multiplying 14.605 by 6 and dividing the total by 12:  6(14.605cm)=84cm 84cm=5inches (12 inches=1 foot, therefore 6 inches=3/4 of one foot).

So now we know that the circumference is 5 inches. If we divide 5 by 3, we can get the diameter in inches:

5/3=1.666~ 1.67 inches

From this result, it can be safely concluded that a ping pong ball is about 1.7 inches in diameter on average.
