1. Find the diameter of a ball that rolls 100 feet after 60 revolutions.
Andre45 [30]

Answer:

Correct option: C (it is missing the point)

0.53

Step-by-step explanation:

When a ball rolls one revolution, the distance travelled is the length of its circunference, that is:

Circunference = pi * diameter

So, to solve this question, we can use a rule of three:

1 revolution -> pi * d

60 revolutions -> 100 feet

100 = 60 * pi * d

d = 100 / (60 * pi) =  0.53 feet

Correct option: C (it is missing the point).
