In bowling, the distance from the foul line to the headpin is 60 feet. A bowling ball has a radius of about 4.3 Inches. How many times must a ball rotate in order to strike the head pin

about 26.6 times

Step-by-step explanation:

The circumference of the ball is found from ...

C = 2πr = 2π (4.3 in) ≈ 27.02 in

There are 12 inches per foot, so the 60 foot distance of interest is ...

(60 ft) * (12 in/ft) = 120 in

In terms of ball circumference, that distance is ...

(120 in) / (27.02 in/rotation) ≈ 26.6 rotations

If the ball starts rotating at the foul line, it will turn about 26.6 times before reaching the head pin.
