The distance around the wheel of a truck is 9.42 feet .what's the diameter of the wheel
kap26 [50]
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
