Step-by-step explanation:
True. The domain of the function gives all real numbers.
awwww..... that's what happens if you can't restrain yourself from judgment to one person . it will imprint on itself nor the sayings .
Well, if the radius is 10, then the circumference is
![\frac{2*10*22}7=\frac{440}7](https://tex.z-dn.net/?f=%5Cfrac%7B2%2A10%2A22%7D7%3D%5Cfrac%7B440%7D7)
What's the unit? Either way, 22 rev. per minute means each minute you go by
![22*\frac{440}7=\frac{9680}7](https://tex.z-dn.net/?f=22%2A%5Cfrac%7B440%7D7%3D%5Cfrac%7B9680%7D7)
units per second. Now you got the linear speed, just find out the time by dividing the distance by the speed!
So, what's the unit for the radius?
