Answer:
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
Step-by-step explanation:
the radius: r^2 = 81
r =9
c = 2*pi*r
= 2 * pi * 9
= 18 *pi
Answer: 18*pi or approximately 56.62
$1.25 because if you bought 2 packs of them it would be $2.50 so you would be 0.09 cheaper
Your answer woild be 3×8+2 and if solved equals 26
