R = 2x + 9y [ Given ]
When,
★ Substituting the values in the above equation
=> 13 = 2x + 9 × 3
=> 13 = 2x + 27
=> 13 - 27 = 2x
=> -14 = 2x
=> x = -14/2

If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.
Step-by-step explanation:
As we know the circumference of a circle is 
The radius of the hub cap needs to be devised to determine the area


centimeters
Area of the hub cap = 
Substituting the devised value of r in the above equation, we get -

square centimeter
If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.
