Answer:

The slope of #7 is 2 an the slope of #8 is -3.

Step-by-step explanation:

In order to find the slope, you can use the slope formula.

m (slope) = (y1 - y2)/(x1 - x2)

Then you can use any two points in order to solve.

m (slope) = (y1 - y2)/(x1 - x2)

m (slope) = (3 - -3)/(2 - -1)

m (slope) = 6/3

m (slope) = 2

m (slope) = (y1 - y2)/(x1 - x2)

m (slope) = (4 - 7)/(-1 - -2)

m (slope) = -3/1

m (slope) = -3

The formula for the volume of a cone is V = jarh, where V is the volume, r is the radius, and h Is the heightWhat is the volume

olga nikolaevna [1]

Given:

The radius, r=4x

The height,

$h=21xy^2$

To find the volume of the cone:

The volume of the cone formula is,

$V=\frac{1}{3}\pi r^2h$

Substitute the values of r and h in the above formula we get,

$\begin{gathered} V=\frac{1}{3}\pi\times(4x)^2\times21xy^2 \\ =\frac{1}{3}\pi\times16x^2\times21xy^2 \\ =\pi\times16x^2\times7xy^2 \\ =112\pi x^3y^2 \end{gathered}$

Hence, the volume of the cone is

$V=112\pi x^3y^2$

Thus, the correct option is option D.
