Answer:
37.69
Step-by-step explanation:
Since the diameter is 12, the Radius is 6
Circumference equation: 2pi(r)
So we plug it in
2pi(6)
That gives us 37.699
If you need to round, then it would be 37.7.
I really hope this helps!!!
Answer:
It's B
Step-by-step explanation:
Complex graphs are just like regular graphs so when doing stuff like midpoint and distance equations you should leave out i.

Answer:
(3, 2), (2, 3)
Step-by-step explanation:
x + y = 5
xy = 6
Solve the first equation for x.
x = 5 - y
Substitute 5 - y for x in the second equation.
xy = 6
(5 - y)y = 6
5y - y² = 6
y² - 5y + 6 = 0
Factor.
(y - 2)(y - 3) = 0
y - 2 = 0 or y - 3 = 0
y = 2 or y = 3
Now substitute 2 for y in the first equation and solve for x.
x + y = 5
x + 2 = 5
x = 3
One solution is x = 3; y = 2, or (3, 2).
Now substitute 3 for y in the first equation and solve for x.
x + y = 5
x + 3 = 5
x = 2
Another solution is x = 2; y = 3, or (3, 2).
Answer: (3, 2), (2, 3)
