false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
