A table tennis ball is approximately 40 millimeters in diameter. The handball used by an Olympic women's team has a diameter of about 17 millimeters. What is the difference in the circumferences of the balls?

Final answer:

The difference in the circumferences of a table tennis ball and an Olympic women's handball is approximately 72.25 millimeters, calculated by subtracting the smaller circumference from the larger one.

Step-by-step explanation:

The question asks about the difference in the circumferences of two balls of different diameters. The circumference of a circle (which in this case, is the same as the circumference of a sphere or ball) can be found using the formula C = πd, where C is the circumference and d is the diameter of the circle.

First, calculate the circumference of the table tennis ball:

C = πd = π * 40 mm ≈ 125.66 mm (using π ≈ 3.14159)

Next, calculate the circumference of the handball:

C = πd = π * 17 mm ≈ 53.41 mm

To find the difference in circumferences, subtract the circumference of the handball from that of the table tennis ball:difference = 125.66 mm - 53.41 mm ≈ 72.25 mm.

The difference in the circumferences of the table tennis ball and the handball is approximately 72.25 millimeters.
