We know, Volume of a Cone = πr² h/3
v = 3.14 * (11)² * 4.5/3
v = 3.14 * 121 * 1.5
v = 569.91 in³

In short, Your Answer would be Option C

Hope this helps!

You want to find the equation for a line that passes through the point (3,-4) and has a slope of -1/2.

Mashcka [7]

Answer:

$y = -\frac{1}{2}x -\frac{5}{2}$

Step-by-step explanation:

We are given;

A point where the line is passing through as (3, -4)
The slope of the line -1/2

We are required to determine the equation of the line;

Note that, one way we can get the equation of a straight line is when we are given a point where the line is passing through and its slope.
Thus, in this case, we can determine the equation;

Taking another point (x, y)

Then; (x, y) , ( 3, -4) and slope -1/2 can give us the equation;

That is;

$\frac{y+4}{x-3}=-\frac{1}{2}$
