The distance around the wheel of a truck is 9.42 feet. what's the diameter of the wheel

To solve this problem, you must follow the proccedure that is shown below:

1. You need to apply the formula for calculate the perimeter of a circle, which is:

P=2πr

P is the perimeter of the circle (P=9.42 feet).

r is the radius of the circle.

2. Now, you must clear the radius "r" from P=2πr, as below:

P=2πr

r=P/2π

3. When you substitute the values, you obtain:

r=P/2π

r=9.42 feet/2π

r=1.49 feet

4. Now, you can calculate the diameter (D):

D=2r

D=2 (1.49 feet)

D=2.98 feet

What's the diameter of the wheel?

The answer is: 2.98 feet
