Question

The diameter of one circle is represented by 12x. The diameter of another circle is represented by 6x square y. What is the radii of the two circles.
A.2 xsquare y
B. 2x:y
C. x:2y
D. 2:xy

Answer 1

The radius is half of the diameter. So the first step is to halve the diameters of both circles.

Answer 2

ok, 6 and 3x

Answer 3

Close. It would be \(6x\) and \(3x\sqrt{y}\)

Answer 4

I don't understand the next step

Answer 5

I am thinking my answer should be B. 2x;y for the ratio

Answer 6

Well it seems that they want you to simplify. It would look like this \[\large \frac{6x}{3x\sqrt{3}}\]

Answer 7

ok

Answer 8

So can you simplify that?
