Answer:
(x-{-2})^2+(y-{4})^2={36}
Equation:
x^2+y^2=r^2
r=radius
Blank following x/y is flipped center(of circle) coordinate for x/y
 
        
             
        
        
        
Answer:
sinY = 
Step-by-step explanation:
sinY =  =
 =  =
 = 
 
        
             
        
        
        
For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

Where:
m: It is the slope
b: It is the cut point with the y axis
We have the following equation:

So the slope is 
By definition, if two lines are parallel then their slopes are equal, so a parallel line would be of the form:

We substitute the given point and find "b":

Finally, the equation is:

Answer:
Step-by-step explanation:
Area of circle=Pi times radius^2
Diameter is half of radius=8.4
Pi*8.4^2=221.670777637
Hope this helps!
