Under the rules of the United States Golf Association the volume of a golf ball cannot be less than 2.48 cubic inches.
A. calculate the radius of this golf ball.
B. Calculate the circumference of this golf ball

• Math -

(4/3)πr^3 ≥ 2.48
r^3 ≥ .592056...
r ≥ .8397 inches

circumference of ball is the circumference of circle with radius .8397
= 2πr
= 5.276 inches
