The circumference of the circular end is 8 pi = approx. 25.1 ft. In your mind's eye, slit the cylinder along its length and flatten it out. You now have a rectangle that is 25.1-ft long and 7-ft wide. Its area is the surface area of the original cylinder = approx. 175.9 sq.ft.

What is the surface area of a cylinder?
The surface area of a cylinder is 2πrh + 2πr². The variable r is the radius and h is the height.2πr² is the area of the top and bottom parts of the cylinder.2πrh is the area of the round circular part.
What is the formula for calculating total surface area of a cylinder?
A cylinder has two circular ends, then the long side surface, which is actually a rectangle if you flatten it out. You need the radius of the circular end (distance from the middle to the edge), and the height of the cylinder to work out the surface area. Doing the circular ends first, the surface area is given by the formula PI x radius squared. PI is 3.1415 for normal use. There are two ends, so count the answer twice. The side surface is a rectangle with one side of the height of the cylinder, and the other side the circumference of the circular end. The circular end length is 2 x PI x radius of the circular end. Now multiple that answer by the height of the cylinder. Finally add together the area of the two ends (don't forget to count both), and the area of the rectangle making up the long side, nd that's your answer.

What is the formula for finding the surface area of the wall of a cylinder?
Divided into 3 sections (the rounded middle-section and the two circular ends), the surface afrea is equal to the area of the circular end multiplied by two (which equals pi X the radius of the circle squared) plus the circumference of the circular end multiplied by the length of the cylinder. Therefore total surface area = 2(pi X radius squared) + length(pi X 2 X radius)
