A truck tire travels about 11 feets in 1 full rotation. What is the diameter of the wheel, to the nearest inch?

C = pi * d

11 = 3.14 * d
11/3.14 = d
? = d

To find the diameter of the wheel, you need to know the circumference of the wheel. The circumference is the distance around the circle formed by the wheel.

Given that the tire travels about 11 feet in 1 full rotation, we can calculate the circumference using the formula:

Circumference = Distance traveled in 1 full rotation
Circumference = 11 feet

Now, we can use the formula for the circumference of a circle, which relates the circumference to the diameter (D):

Circumference = π * D

Rearranging the formula, we can solve for the diameter:

D = Circumference / π

D = 11 feet / 3.14 (using an approximation for the value of π)

Calculating this, the diameter of the wheel is approximately:

D ≈ 3.50 feet

To convert this value to inches, simply multiply by 12 inches/foot:

D ≈ 3.50 feet * 12 inches/foot

D ≈ 42 inches

Therefore, the diameter of the wheel is approximately 42 inches.
