A street that is 156m long is covered in snow. City workers are using a snowplow to clear the street. A tire on the snowplow has to turn 39 times in traveling the length of the street. What is the diameter of the tire? Use the value 3.14 for Pi . Round your answer to the nearest tenth. Do not round any intermediate steps.

    Then, use the formula, Cirmufrence = pi * d Where d is the diameter.

    you have the circumference of the tire as 156/39=4 C=pi*d d=C/pi where d is diameter, C is circumerference, as khan said

    It's 4. like i said. 4m is the circumfrence.

    156 = 39 * ( pi * D) ->D = 156/ 39 pi = 1.27m
