I believe that when finding the radius of a circle you half the diameter, but when finding the circumference of a circle you need to multiply the diameter (14cm) by pi.
So 14xpi= 43.98229715
But it can be simplified/ rounded to 44cm.
Of course I might be incorrect so do please correct me if I am wrong.

Answer:
16.5x == 465.3
Step-by-step explanation:
To find the rate , take the number of miles and divide by the gallons
rate = 465.3 / 16.5
Let the rate be x
x = 465.3 / 16.5
Multiply each side by 16.5
16.5x = 465.3
