Well for the first equation you plug in the numbers for the variable of pi and r. Since the value of pi is 3.142 and the value of r is 5. You plug it in to the equation like this, C=2(3.142)(5). Then whatever you get then is your answer for the first part.

For the second equation you basically do the what you did in the first equation. You plug in the values for the variables of pi and r. Which are also 3.142 and 5. Therefore the equation would look like this, A=(3.142)(5)^2. And then when you multiply it whatever you get is your answer.

Which statement best describes if the relation (c, f) is a function?

mihalych1998 [28]

Answer:

The graph is not a function of x because the line x=0 intersects the graph at two points

Step-by-step explanation:

For any function of x, x can only map to one point. What this means is that for every x value, it only results in one y value. If you can input x into the relation's equation and get two outputs, the relation is not a function.

We can check if an x value maps to two points by using a vertical line, such as x=0, and if it crosses the relation at two points, the relation is not a function.

Since x=0 crosses the line at two points, it means that this relation is not a function.
