Answer:

Circumference = 10π

Step-by-step explanation:

First identify the circumference formula as such:

2πr (where r ⇒ radius, π ⇒ pi)

Knowing 2 times the radius (2r) in the formula can be rewritten as the diameter, the formula itself can be rewritten as:

πd (where d ⇒ diameter, π ⇒ pi)

If we know the diameter = 10 inches, substitute in the circumference formula πd to get:

π * 10 inches = 10 * π inches = 10π inches

What is the slope of the line that passes through the pairs of points (-6,8) (2'3)

Alecsey [184]

Im pretty sure the answer is D, because if i used the right formula,
$\frac{y2 - y1}{x2 - x1}$
you should get this in the formula
$\frac{8 - 3}{2 - ( - 6)}$
$\frac{5}{8}$
a 2 subtracting a negative 6 makes it a positive, meaning your just adding 6 plus2, to get 8
