We are quite familiar that the two bases joining the combination of rectangular like shape and two circular bases is the shape of a cylinder known as cylindrical shape. The Curved Surface Area of the Cylinder = 2πrh As the rectangular paper was used in wrapping the Can, we have the knowledge that area of rectangle = area of the curved surface of the Cylindrical Vessel = l × b = 2πr × h h is the breadth of the rectangle = Height of the cylindrical can. The next thing that you need to do is to remove the paper and then cut the cylindrical paper where you need to make sure to cut it parallel to its axis and then make it rectangular in shape.įrom the figure we find that the length of the cylinder = the circumference of the base = 2πr. You can also try to clip paper from bottom to top so as to match the shape of your can. It is important to ensure that the paper is wrapped in such a way so that it accurately fits with this cylindrical can. If you wish to calculate the curved surface of the geometrical figure, then the first thing to do is to take a sheet of paper and then wrap a cylindrical can. Frustum of a cone: formation and formulas ( slant height: volume: CSA: TSA).Here, in each base has a radius (r.) Calculating the volume and surface area of the cylinder is possible from the measurement of height and radius. ![]() ![]() When the two circular bases joins the line at the center, it is known as the axis of the cylinder.Īs seen in the figure above, height (h) happens to be the perpendicular distance between the two bases. A cylinder is formed by the base and sides. If cylinder is unrolled, then it gives a flattened look of a rectangle. When it comes to the circular bases, it is always found to be parallel as well as congruent to one another. It is also defined as a rectangular that has rectangular bases. CylinderĪ cylinder happens to be a close shape that has got two parallel bases which has a circular shape in general and is connected by two parallel sides. In this chapter, you will be able to learn about cylinder and the capacity of the most used shapes. The word ‘cylinder’ is derived from the Greek word, ‘kulindros’ which means a tumbler. One of the most commonly sighted geometric shapes is a cylinder where you can find it in fuel containers, gas tanks and even coffee mugs. ![]()
