32r =18
R=3a-18
R= 3(32)-18
R=96-18

Answer:
Your question doesn't make sense.
Step-by-step explanation:
R = 12 inches, the radius of the wheel.
The circumference of the wheel is
2πr = 2π(12) = 24π inches.
WHen the wheel makes 15 revolutions, the car will travel 15 times the circumference, which is
15*(24π) = 360π inches = 1131 inches.
Answer: 1131 inches
