Final answer:
To calculate the distance Jimmy's truck travels, we can use the formula for the circumference of a circle. By multiplying the circumference by the number of revolutions, we can find the distance traveled in feet.
Step-by-step explanation:
To calculate the distance the truck travels, we need to first calculate the circumference of the tire. The circumference of a circle is given by the formula C = 2*pi*r, where C is the circumference, pi is a mathematical constant approximately equal to 3.14, and r is the radius of the circle. In this case, the radius of Jimmy's truck tires is 39 inches, so the circumference is 2*3.14*39 inches. To convert this distance from inches to feet, we divide by 12, since there are 12 inches in a foot. So, the total distance the truck travels is (2*3.14*39)/12 feet per revolution. If the wheel makes n revolutions, the total distance traveled is n times this value.
