Answers
Answer 1
Answer:
The surface area of a right cylinder equals 
As you can see in the attached picture, the surface area consists of two equal circles (bottom and top one) and area that would look like a rectangle, if "unraveled".
The formulae for the surface area of the circle is
. You have to multiply it by two and add to the area of the "rectangle", which equals 
where 
is the circumference of the circle and 
is the height of the cylinder.
