The line L cuts the y-axis at (0,5). L also passes through the point (2, 1).
Find the equation of the line which is parallel to L and which passes through the
point (3,0).

ok thats very interesting

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
