What is the circumference of a tennis ball

The circumference of a tennis ball is determined by its diameter. According to the International Tennis Federation (ITF) regulations, the diameter of a tennis ball for official play must be between 6.54cm and 6.86cm. Using the formula for the circumference of a circle (C = πd), we can calculate the circumference of a tennis ball within the specified diameter range:

For a ball with a diameter of 6.54cm: C = π x 6.54cm ≈ 20.72cm
For a ball with a diameter of 6.86cm: C = π x 6.86cm ≈ 21.64cm

Therefore, the circumference of a tennis ball used in official play ranges from approximately 20.72cm to 21.64cm.
