What is the exact circumference of a circle with a radius of 12 inches?

Anestetic [448]

We can get the circumference of any circle in terms of the radius with this formula. C = 2 $\pi$ r.

Where r is the radius of the circle.

And we will use 3.14 for $\pi$ .

Plug in all the values.

C = 2 * 3.14 * 2

C = 12.56

So, the circumference of the circle is 12.6 inches when rounded to the nearest tenth.

For what values of b the relation R:{(b^2, 5), (5b, 6)} is not a function?

xenn [34]

Answer:

B=5,0.

Step-by-step explanation:

It's not that hard. It's just that it might throw you off a bit with the R and the other things. Functions if you don't remember are where the coordinates don't have the same x and y. So since the y1 and y2 are different then to make it not a function, you have to make x1 and x2. To make it that b would have to be = to 5 and 0.
