How many times does a tire with a diameter of 36 in. rotate when it travels a mile? **Tip: As there are 63,360 in. in each mile, 63,360 divided by circumference = number of full rotations. Round up to the next whole number.
The circumference of a tire with a diameter of 36 inches can be calculated using the formula: C = π x d, where C is the circumference, π is approximately 3.14159, and d is the diameter in inches.
C = 3.14159 x 36 = 113.09724 inches
Next, we divide the total inches in a mile (63,360) by the circumference of the tire to find the number of full rotations:
63,360 / 113.09724 ≈ 561.06
Rounding up to the nearest whole number, a tire with a diameter of 36 inches rotates about 562 times when traveling a mile.
