Answer:
Yes
Step-by-step explanation:
Is proportional because it has 0,0 so it is proportional (sorry if is not helful this is was my teacher taught me hope it is helpful.
these are just two semi-circles, one with a diameter of 22 and the other with a diameter of 30 - 22, or 8, and therefore their radius are 11 and 4 respectively.
