X = -7
3 • 7 = 21
-3 • (-7) = 21
If you multiply two negative numbers you’ll end up with a positive. Thus, - 3 (-7) = 21.
System of equations:


The intersection point for this is <em>(4,11)</em>.

Answer:
Area= 64pi or 201.06
Circumference: 16pi or 50.265
Step-by-step explanation:
Area= \pi r^{2}
pi (8)^2 = 64pi or 201.06
Circumference= 2pir , 2(pi)8 = 16pi or 50.2
