Circumference of whole circle =
$\pi \times 3 \times 2$
360÷20=18
$\frac{1}{18} \times 6\pi = \frac{1}{3} \pi$
hence length of arc = 1/3 pi

First, plug in 5 for x:

| -5 * 5 + 12 | = |-25 + 12| = |-13|

Those two lines are absolute value, which measures the distance from the number to 0 on a number line. This distance is always positive.

The distance from -13 to 0 on a number line is 13. The answer is 13.

Y= -2+4

If X equals -2, you want to plug -2 in for X.
