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
