Intro

step-by-step explanation:

the answer is a if my teacher taught me correct

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!

look at the picture i have filled out a table for it. hope this .
