what is the diameter of a table tennis ball: what is the 40 mm diameter of a tennis ball: 6.8 cm
To find the diameter of a table tennis ball, the first step is to identify the measurement unit being used. In this case, the table tennis ball is commonly measured in millimeters (mm).
The diameter of a table tennis ball is 40 mm. This means that if you were to measure across the widest part of the ball, you would get a distance of 40 mm.
On the other hand, the diameter of a tennis ball is typically measured in centimeters (cm), not millimeters.
Converting 40 mm to centimeters, we can divide by 10 since there are 10 millimeters in 1 centimeter.
40 mm ÷ 10 = 4 cm
So the diameter of a 40 mm table tennis ball is 4 cm, not 6.8 cm. It's important to use the correct measurement unit when comparing or converting measurements.
