No.
-22/9 is a fraction with integer numerator and denominator. That is the definition of a rational number. When written in decimal form, it is an infinitely repeating decimal with a single repeating digit: 4. Any repeating decimal is a rational number. It is only irrational if it doesn't repeat.
 
        
             
        
        
        
Left and right affect domain. (x)
Up and down effects range. (y)
So,
-2+5 (because the right of the number line is an increase)
7-2 (because you are decreasing by going down)
You are left with:
R'(3,5)
I hope this helps!

Area=(Theta/2) * r^2 This should be it, obviously Theta is your angle and you should use radiants in theory.
        
             
        
        
        
Add 22+14. Then multiply 12. Then divide by 2
