Step-by-step explanation:

to calculate circumference:

$2\pi \: r$

if the diameter is 16 then the radius would be 8.

$2\pi \:r \\ = 2\pi(8) \\ = 16\pi \\ =Rationalize(50.26548245744) \\circumference = 50.27$

to calculate the area of a circle:

$\pi {r}^{2} \\ = \pi( {8})^{2} \\ = Rationalize(201.06192982975) \\ area = 201.06 \: ^{2}$

Answer: - 1/5

Step-by-step explanation:

-1/3= -0.333333

1/2= 0.5

-1/5= -0.2

1/4= 0.25

When you compare them, you see that -0.2 is closer to 0. Since -0.2 is equivalent to -1/5, -1/5 is the answer.

Answer:

$\frac{2}{x-4}$

Step-by-step explanation:

$\frac{2x+4}{x^2-2x-8}$

Factor both the numerator and denominator

$\frac{2(x+2)}{(x-4)(x+2)}$

The $x+2$ 's cancel out

The equation in its simplest form is $\frac{2}{x-4}$
