Only Equation I.

Reason: a linear equation in r has r to the first power (form y = k r + b).
I: C = 2πr is linear in r.
II: A = πr^2 is quadratic (r^2).
III: V = (4/3)πr^3 (or as written with r^2) is not linear (involves r to a higher power).

If III was meant differently, tell me the intended exponents and I’ll re-check.
