IMPORTANT QUESTION [?]
If we clean out our vacuums... does that make us VACUUM CLEANERS?!
If people clean carpets, that makes them carpet cleaners (as a job...)

yes. But it depends on who you ask. So it could be yes and no.

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.
