The volume of an official NBA basketball is approximately 7,100 cubic centimeters (cm³).
This measurement derives from the standard size of an NBA basketball, which has a circumference of about 29.5 inches (75 cm). Utilizing the formula for the volume of a sphere, V = 4/3 × π × r³, where r is the radius, we can calculate the volume. First, we find the radius by dividing the circumference by 2π, leading to a radius of around 11.5 cm. Plugging this value into the volume formula gives us the final volume of approximately 7,100 cm³.
