A standard basketball has a circumference of 30 inches. What is the diameter rounded to the nearest tenth?

Answer 1

To find the diameter of the basketball, we use the formula for circumference: C = π*d

Given that the circumference is 30 inches, we can plug in the values:

30 = π*d

To isolate d, we divide both sides by π:

d = 30/π

Approximating π to 3.14, we have:

d ≈ 30 / 3.14 = 9.55 inches

Rounding to the nearest tenth, the diameter of the basketball is 9.6 inches.
