Answer:
D.
Step-by-step explanation:
The point-slope form of a line is given by:
The line given to us has equation; .
The slope of this line is -4. The of the line perpendicular to this line is the negative reciprocal of the slope of the given line.
Our slope of interest is therefore;
Since the point goes through (-2,7), we have .
We plug in the slope and the point into the point-slope formula to obain;
The required equation is:
To find the volume of a cone, you use the formula 
.
Radius squared would be 36 in our case and 36 times 3.14 is 113.04. 6 thirds is also two, so multiply that by two and you would get 113.04 x 2 = 226.08. So, your answer would be 226.08 cubic meters of dirt.
