, where r is the radius of the base and l is the slant height.
2. The slant height l is found as follows:

4. The answer is C
Answer:
m= rise/ run
Step-by-step explanation:
We can find the slope by
m= rise/ run
= change in y/ change in x
= ( y2-y1)/(x2-x1)
= vertical change/ horizontal change
It's dependent on the context. A book may ask you to find the f'(x) of a function and you may have to use a u sub in your problem which requires you to find the dy/dx of what you substitute. So in this case both would be used.
