Answer:

Step-by-step explanation:

X values cannot repeat in a function, 3 is used as an X value twice in A, and therefore cannot be a function.

If this is graphed, you can use the vertical line test, if a vertical line on any point goes through other points, it is not a function.

In this case, just check if X repeats.

If a circle has a Diameter of 4m and a Radius of 4 units. Then what is Circumference and Area of the circle?

Fiesta28 [93]

Answer & Step-by-step explanation:

$Circumference=d\pi \\Area=r^2\pi$

The diameter of the circle is 8 m and the radius of the circle is 4 units. So, now we have to plug in the numbers so we can find the circumference and the area of the circle.

$Circumference=(8)\pi$

$Circumference=25.12$

So, the circumference of the circle is 25.12 m.

$Area=(4)^2\pi$

$Area=16\pi$

$Area=50.24$

So, the area of the circle is 50.24 units².
