Parallel lines have the same slope. So if you know the slope of a line in question, or you can calculate it, then you know the slope of any line parallel to that line.
y=mx+b whatever multiplies x in this form is the slope
the slope is -5/4
No. If you have more than two points for a linear function any two points can be used to find the slope.
108.4 square feet
Assuming the cone has a constant slope, I think it's Pi (about 3.141... Google it) times by the height, times by the radius squared, divide by 3. You may have to use the slope height (use Pythagoras for this), but I think it's just height.
A cone with the radius of 5 cm and slope height of 9 cm has a total surface area of approximately 219.91cm2
We would need one other piece of information to answer it: EG. the angle of the slope, or the radius or diameter of the cone base, or perhaps, the volume of the cone would also help. We need just one of these aforesaid pieces of information in order to calculate height.
It is the length of the slope of a right cone.
The slope can be a fraction.
It depends on what the cone looks like.
the cone base formula
It depends on what the cone looks like.
you find the radius of a cone by the bottom of it or the round part
You find the tangent to the curve at the point of interest and then find the slope of the tangent.
You find the slope of the tangent to the curve at the point of interest.
how can you find the perimeter of a cone i.e. a 3d shape!
