you find the surface area of a circle by first finding the area of the circles/ two ends. you do this by multiplying the diameter by pi then multiply by two, that is both ends put together then you find the area of the flat part by finding out the circumference of the circle ends, then multiply that by the height of the cylinder. circumference= pi times the diameter then add all your calculation together, and you have the surface area of your cylinder :)
The surface area of a cylinder can be derived from the area of rectangle. If you 'unroll' a cylinder you have a shape of a rectangle, similar to a sheet of paper. The width of the rectangle will be the height of the cylinder and the length of the rectangle will be the circumference of the cylinder end.So, Area = length * widthwhere, width = height of cylinder & length = circumference of cylinder end = PI*(Diameter of cylinder)Therefore,surface area of a cylinder = (PI)*(diameter of cylinder)*(height of cylinder)Hope that helps!
Usually when dealing with circles. (surface area of a cylinder, circumference of a circle, volume of a cylinder, etc.)
== == A can is a regular cylinder. It's surface area can be found by finding the area of the ends (finding the area of one end and doubling it) and by finding the area of the side of the can. The ends are circles. The area of a circle is pi times the square of the radius Areacircle = pi x r2 [If you have the diameter of the can, r = d / 2] Find that area and double it. The side surface area of a right cylinder is found by finding the circumference of the cylinder and multiplying by its height. (Think of it as taking the cylinder and cutting it straight up the seam, unrolling the can and finishing the exercise by flattening it out to end up with a rectangle.) Areaside = C x h C = pi x diameter or pi x (2 times the radius) h = Height of can Given the height and the diameter of a can, these ideas can be applied to find its total surface area.
There is no point in giving the circumference to 14 decimal places but no information about the height. You would have been far better giving the circumference to 2 decimal places and the height. As it is, the question cannot be answered.
Some of many examples are:- Finding the circumference of a circle Finding the area of a circle Finding the surface area of a sphere Finding the volume of a sphere Finding the surface area of a cylinder Finding the volume of a cylinder Finding the volume of a cone Finding the surface area of a cone
The circumference of a circle divided by its diameter is the value of pi and pi has a wide range of uses some of which are:- Finding the volume of a sphere Finding the surface area of a sphere Finding the volume of a cone Finding the volume of a cylinder Finding the area of a circle Finding the circumference of a circle
you divide the surface area by the circumference.
Some of the many applications that pi is used in geometry are as follows:- Finding the area of a circle Finding the circumference of a circle Finding the volume of a sphere Finding the surface area of a sphere Finding the surface area and volume of a cylinder Finding the volume of a cone

Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
You can't tell. It can be anything. A cylinder wth a circumference of 52 can have any length. It could be 0.001 long, or it could be 35 million long, or less, or more, or anything in between. All of these different cylinders could have the same circumference, but they all have different surface areas. The surface area is (circumference) x (length). So the surface area of your cylinder is 52 for every 1.0 unit it is long.
4*pi*r2. because surface area is equal to circumference of circle.
The surface area of a cylinder can be derived from the area of rectangle. If you 'unroll' a cylinder you have a shape of a rectangle, similar to a sheet of paper. The width of the rectangle will be the height of the cylinder and the length of the rectangle will be the circumference of the cylinder end.So, Area = length * widthwhere, width = height of cylinder & length = circumference of cylinder end = PI*(Diameter of cylinder)Therefore,surface area of a cylinder = (PI)*(diameter of cylinder)*(height of cylinder)Hope that helps!
Take the circumference and multiply it by it's height to get the lateral surface area.
2 X Pi X radius X height = area Circumference X height = area (times two if you want inside and outside assuming the walls are of zero thickness)
