What is the area of a cylinder? The base of the cylinder is at 0, and the cylinder's height is from the center of the base, out to the circumscribing circumference. The area is π x radius.
In the middle of the two circular bases, there is a curved surface, which, when opened represents a rectangular shape. This curved surface is also called lateral surface. The different parameters that are used to calculate the cylinder area include radius, height, axis, base, and side. The radius of the cylinder is defined as the radius of the circular base. The height of the cylinder is calculated by measuring the perpendicular distance between two circular bases, and the line that joins the centre of the base is called the axis.
The area of the cylinder is the total region covered by a cylinder in three-dimensional space. The cylinder area is equal to the sum of the area of two circular bases and curved surface area. In right cylinders, the two circular bases are exactly over each other and the axis line produces a right angle to the base. In case one of the circular bases is displaced and the axis does not produce the right angle to the base, then it is called the oblique cylinder. (Source: byjus.com)
The surface area formula for a cylinder comes from adding up three flat areas - the areas of each circular end and the area of the rectangle that makes up the "tube." The results from the experiment should show that these values (whether using the formula or adding up pieces) should be very similar. They should be identical, however slight error in measurement could result in slightly different surface areas - but with perfect measurement the results should be the same.
If you have ever seen a can of soda, you know what a cylinder looks like. A cylinder is a solid figure with two parallel circles of the same size at the top and bottom. The top and bottom of a cylinder are called the bases. The height [latex]h[/latex] of a cylinder is the distance between the two bases. For all the cylinders we will work with here, the sides and the height, [latex]h[/latex] , will be perpendicular to the bases. (Source: courses.lumenlearning.com)
