Step-by-step explanation:

Circumference =π×diameter

30π=π×diameter

Diameter=30π÷π

Diameter=30in

B. 30 inches

Reason:
The radius of the circle would be 15pi because 30pi divided by 2 would be 15pi (the formula for circumference is 2 x pi x radius). Diameter would be 2x the radius, so 15pi x 2 = diameter = 30

Determine the slope of the line that contains the given points <br><br> J(-5, -2), K(5, −4)

Irina-Kira [14]

Answer:

$-\frac15$

Step-by-step explanation:

Hello!

We can utilize the slope formula to find the slope.

Slope Formula: $S = \frac{y_2-y_1}{x_2-x_1}$

Remember that a coordinate is written in the form (x,y)

<h3>Find the Slope</h3>

$S = \frac{y_2-y_1}{x_2-x_1}$
$S = \frac{-4-(-2)}{5-(-5)}$
$S = \frac{-2}{10}$
$S = -\frac15$

The slope of the line is $-\frac15$ .
