What is the formula for the circumference of a circle?
Juli2301 [7.4K]

Answer:

C = pi * d = 2 * pi *r

Step-by-step explanation:

The circumference of a circle is the distance around the circle.  It can be found by multiplying the diameter times pi.

C = pi * d

We can replace the diameter with twice the radius

C = pi * 2 * r = 2 * pi *r

Simplify this expression
kompoz [17]
The first step for solving this problem is to know that in order to divide by a fraction,, we must multiply by the reciprocal of that fraction. This will look like the following:
\frac{x+2}{ x^{2} -6x-16} × 9x
Write -6x as a difference.
\frac{x+2}{ x^{2} +2x-8x-16} × 9x
Factor out x from x² + 2x.
\frac{x+2}{ x X (x+2)-8x-16} × 9x
Factor out -8 from -8(x + 2).
\frac{x+2}{ x X (x+2)-8(x+2)} × 9x
Factor out x + 2 from the denominator (bottom) of the expression.
\frac{x+2}{(x+2)X(x-8)} × 9x
Reduce the fraction with x + 2
\frac{1}{x-8} × 9x
Finally,, calculate the product to find your final answer.
\frac{9x}{x-8}
This means that the correct answer to your question is going to be option B.
