Answer:

Step-by-step explanation:
we know that
The equation of the line in slope intercept form is equal to

where
m is the slope
b is the y-intercept
so
1) Find the slope of the given line 
The slope is 
2) Find the y-intercept of the given line 
The y-intercept is 
therefore
The equation of the line with


is equal to

Answer:

Step-by-step explanation:
<u>Step 1</u>:-
<u>Formula:-</u>
The total surface area of cone is


........(1)
<u>Step 2:-</u>
Given slant height 
and radius of the circle (base) = 2
substituting these values in equation (1)

on simplification, we get
