Question

A street that is 164m long is covered in snow. City workers are using a snowplow to clear the street. The snowplow has tires that are 2.1m in diameter. How many times does a tire have to turn in traveling the length of the street? Use the value 3.14 for π. Round your answer to the nearest tenth. Do not round any intermediate steps.

Answer 1

The number of times the tires will have to spin is 24.9 times. How I got this was by finding the circumference, the equation in this case where pi is 3.14 is 3.14(2.1). That equals 6.594, then you divide 164 by 6.594 to get 24.87109 blah blah and you round that up to 24.9.
