Since we are dealing with a radical then x - 5 ≥ 0, for real values
x = 4 is less than 5 , hence is not in the domain
Step-by-step explanation:

use s=r0
but first convert 360 degree to radian
you will get 6.284 radian
then you substitute and get the answer!
12= r (6.284)
r= 1.91 cm
Whats your geometry problem? i dont understand the question
Answer:
Is this algebra, or does "x" represent multiplying?
