How do u find the circumference of a circle without the diameter or radius just then arc length?

In order to find the circumference you will use the arc length to find radius.

Use the equation

arc length L =  r*Θ , where  Θ is in radians.

Re-arrange the equation to get r = L / Θ

Finally use radius to solve for circumference using

C = 2 π r

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
