Answer:
Step-by-step explanation:
If this is a true or false statement then TRUE

The answer is D because a proportional relationship on a graph would start on (0,0), so A and B cannot be the right answer. On answer C, the relationship starts as 4x=y but changes, so this cannot be a proportional relationship because the relationship needs to be constant. Answer D is the right answer because the proportional relationship remains constant (1.5x=y).
Answer:
16 pi ft^2
Step-by-step explanation:
C = 2 * pi *r
4 pi = 2* pi *r
Divide each side by 2pi
4pi/2pi = 2pi r/2pi
2 = r
We can find the surface area
SA = 4 pi r^2
= 4 * pi * (2)^2
= 16 pi ft^2
