The only graph that shows a proportional relationship is the line that crosses the origin point (0,0). The other graphs are linear functions but not not proportional relationships. The general form of a proportional relationship is y = kx, where k is the proportionality constant.
Answer:
it would be C because they don't give enough information
V(cylinder)= πr²h
d=2r,
d is diameter, r is radius.
When diameter is tripled, a new diameter D=3d,
new radius R=3d/2=(3*2r)/2=3r
R=3r
V(new cylinder)= πR²h = π(3r)²h=9πr²h
V(new cylinder)/V(cylinder)=9πr²h/πr²h=9
Volume new cylinder 9 times more the volume of old cylinder.
