1. what is the linear distance traveled in one revolution of a 36 in. diameter wheel?

formula	substitute/solve	final answer

Explanation:

Step1: Recall circumference formula

The linear distance traveled in one - revolution of a wheel is equal to its circumference. The formula for the circumference of a circle is $C=\pi d$, where $d$ is the diameter of the circle.

Step2: Substitute the given diameter

Given $d = 36$ inches. Substitute $d$ into the formula: $C=\pi\times36$.

Step3: Calculate the result

$C = 36\pi\approx36\times3.14 = 113.04$ inches.

Answer:

$113.04$ inches
