Question

A street that is 330 ft long is covered in snow. City workers are using a snowplow to clear the street. A tire on the snowplow had to turn 30 times in traveling the length on the street. What is the diameter of the tire?
Use the value of 3.14 for pie.

Answer 1

The Answer is 3.5 3.5 x 3.14 = 11 (here i'm using the perimeter of a circumference formula: pi x diameter = perimeter) 11 x 30 = 330 (And that perimeter had to cover that distance in 30 laps so you could get the answer dividing).
