Use these equations when converting polar equations to parametric equations:


We know that  , so substitute that into both equations for x and y.
, so substitute that into both equations for x and y.


Now, replace  with any variable that you want to represent the parametric equations in. I'll use the standard variable,
 with any variable that you want to represent the parametric equations in. I'll use the standard variable, 


Thus,  represented in parametric form is:
 represented in parametric form is:

Answer:
880
Step-by-step explanation:
2/5 times 2200
 
        
                    
             
        
        
        
If one inch = 2.54 centimeters, then 45 centimeters divided by 2.54 centimeters will give you the amount of inches the piece of wood needs to be.
45/2.54 = 17.72  ---- Rounded to the nearest quarter, would be 17.75 inches.
