To find the circumference you would multiply the diameter by pi(3.14) so you do the opposite. Divide 6 by 3.14 (pi) and you should get your answer: 19.1 or something similar.
You will want to use:
f(x)=3+2x
x equals the amount of weeks, with the multiple of 2 for 2 inches per week, and the 3 is the starting height.
Hope this helps!
