The lateral surface area of a cylinder is just the long side connecting the bases, whereas the total surface area includes both the lateral surface area and area of the two circular bases.

(Imagine a rectangle with the circumfrence of the base as one side and the height as the other being folded around)

(Plus the area of two circles)
The literal difference between surface areas would be the two bases 2πr² if you need that.
28/81 is less than 7/9
28/81 is less than 4/9
The common denominator is 81, so you say 9 can go into 81 nine times, so you multiply 9 by the numerator, so 7/9 is now 63/81 an 4/9 is now 36/81

Answer:
12x+9
Step-by-step explanation:
We may find the perimeter of a shape by adding all of it's side lengths.
We can start by adding 2 sides together.
(5x+2)+(3x+8)=8x+10
Because we don't know the value of x, we can only add together the amount of times that it is multiplied.
Now we add the final side.
(8x+10)+(4x-1)=12x+9
Hope this helps friend.
