Answer:6	36	2.449
Step-by-step explanation: 36 square
 
        
             
        
        
        
Answer:
1) y=(-1/4)x+(11/4)
2) y=(4)x-33
3) y=(2/3)x-11/3
4) y=(5)x-2
5) y=(3)x-7
6) y=(-1/4)x+(6)
Step-by-step explanation:
1) y=mx+b  3=(-1/4)(-1)+b  b= 11/4
2) y=mx+b  -5=(4)(7)+b  b= -33
3) y=mx+b  -5=(2/3)(-2)+b  b= -11/3
4) y=mx+b  3=(5)(1)+b  b= -2
5) y=mx+b  -1=(-3)(-2)+b  b= -7
6) y=mx+b  7=(1/4)(4)+b  b= 6
 
        
             
        
        
        
Your multiplying by -4 each time
-1x-4=4
4x-4=-16
-16x-4=64
 
        
             
        
        
        
Point D is the midpoint of the outer circle that we aim to find the area of
The circle has a diameter of WZ and radii of WC and CZ
We know that YZ=YD=10 cm
Let DC be 

 and CY be 

The radius of the outer circle can be written as 

 or 

 which we can equate to find the value of 





Therefore, the radius of the circle is 

And hence the area of the circle is 

=324
