Answer:
12.99km
Step-by-step explanation:
Using the formula
C=2(pi)(r)
I think it is 6+2 I could be wrong
So, for something to be a function see that we want one x value to correspond to only one y value. Solving for y here gives us:

So we see that for every x, there are actually two y values output, so it is not a function.
Answer: A
Step-by-step explanation:
The solution to the graph of inequality given above is the shaded portion or the shaded part of the graph.
Since the point ( -3, -3) and ( 3, -1 ) are on the point line, and the line is a broken line, the inequality means greater than. That means that solution must be greater than those point. They are therefore not part of the solution.
Point ( 5, -5), where x = 5 and y = -5, according to the graph, the shaded portion does not cover y at -5.
Option C is therefore the correct answer which is within the shaded portion. (1, 5)
