Answer:
The radius is 4.5
Step-by-step explanation:
Well circumfrence is basically
2πr=Circumference
In this case
2πr= 28.26
π is about 3.14
2*3.14*r=28.26
Now combine
6.28r=28.26
Now solve
r=4.5
Sorry if wrong
God bless you
The slope is -1 and y-intercept is at y = -3.
-7y= 7x+21
Divide through by -7:
y = -x - 3
