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
*Please help i don't know how to do this!!*

  • 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
