The diameter of a basketball rim is 18 inches. A standard basketball has a circumference of 30 inches
To find the diameter of a basketball, you need to divide the circumference by pi (π).
Diameter = Circumference / π
Given that the circumference of a basketball is 30 inches, the diameter can be calculated as follows:
Diameter = 30 inches / π
Using the value of π as approximately 3.14159, we can calculate:
Diameter = 30 inches / 3.14159
Diameter ≈ 9.5498 inches
Therefore, the diameter of a basketball is approximately 9.5498 inches.
