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.

Find the slope of the line that passes through the coordinates (3,-6) and (-9,2)

JulsSmile [24]

9514 1404 393

Answer:

-2/3

Step-by-step explanation:

The slope formula is useful for this.

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

m = (2 -(-6))/(-9 -3) = 8/-12

m = -2/3

The slope of the line is -2/3.

The graph shows the two points and a line with a slope of -2/3.
