What the Surface Area of a Cylinder Is
For many students, it’s not a secret that geometry can be quite a tricky subject, especially if they’re not fond of mathematics, but they all need to master this subject to get high grades. There are different things that may confuse you while completing endless geometry assignments, including the surface area of a cylinder. That’s why you should be careful and avoid making everything harder to yourself. The main rule that must be followed to achieve your academic success is to practice a lot. In mathematics, practice and repetition make sense, and this is what can help you get better at geometry.
First, you need to find out more about cylinders and answer a few basic questions. What are they? You can define this figure as a round and straight bar. If you’re more interested in math terms, cylinders are defined as 2 parallel circular and flat surfaces at the end of curved sections. If you find it hard to grab this definition, imagine a simple soda can or candles and you’ll understand what a cylinder is all about. What does it look like? As you already know, cylinders look like round and straight bars.
What about the surface area of a cylinder? It comes when you take into account the outside area of this figure, and you can think of it as the amount of paper that you require to cover a given cylinder completely. For example, if you need to buy this kind of paper in the shop, it’s necessary to calculate this surface area to ensure that you’re getting enough.
The good news is that there is a special formula that can help you end up with the right answer. One of the greatest things about mathematics and geometry is that you have formulas for everything. To find any given surface area, you also need to use a formula, which is a certain combination of 2 calculations.
First, you should calculate the surface area of its curved part, and then it’s necessary to add 2 surface areas of circles. If you forget this formula for any reason, feel free to break apart cylinders into flat and curved areas to find their surface areas before adding.
Basic Steps to Calculate This Area
As a math student, you should already know that the surface area of any geometrical shape is the sum total of its area and all faces. When it comes to the surface area of a cylinder, it’s required to find the areas of all of its bases to add it to a lateral area (area of its height). Don’t forget that you have a simple formula to calculate it fast, which is A = 2πr2 + 2πrh. Basically, there are certain steps involved in this academic task, and they all are discussed below.
First, you need to find the radius of cylinder bases, and take into account that they all have the same area and size so that it doesn’t really matter which one you choose. The next thing that should be done to find the area of a base is to plug a radius into the above-mentioned formula. You also need to double the result obtained to get the area of both bottom and top circles. Multiply the result you get by two to get these areas, which are the ones of both bases.
To calculate the surface area of a cylinder correctly, you should determine the circumference of its circle. This step should be taken to calculate a lateral area or the area of all cylinder sides. It’s easy to achieve this goal because the only thing that has to be done is multiplying a radius by 2π. Besides, you need to multiply the circumference of a circle by the height of your cylinder, as this is what will provide you with a lateral surface area. The latter one should be added to a base area, and once you complete this process, you can rest assured because you get the right answer.
Basic Information about Cylinders
They are quite popular geometrical shapes, which are 3-dimensional objects that have 1 curved side and 2 round flat bases. When you walk into a local grocery store, you can find many cylinders that hold all types of products inside. It’s not a secret that a cylinder is one of the main curved geometric shapes, and you should understand that its surface is formed by points located at a fixed distance from a particular line segment or its axis. Think about a circular prism because both a solid shape and a surface created inside is a cylinder. It’s worth mentioning that the volume and surface area of a cylinder have been known for a long time.
When studying differential geometry, it’s possible to define this shape in a broader manner, such as any ruled surface spanned by a 1-parameter group of parallel lines. When dealing with cylinders with ellipses, hyperbolas, or parabolas as their cross sections, keep in mind that they are called accordingly (elliptic, hyperbolic, and parabolic).
What about important measurements? When getting more information about cylinders, you need to find out more about their 2 key measurements. Think about simple soda cans, and you’ll notice that they have the same height, while their circles that form bottoms and tops also have the same size. The main reason is that they have the same radius, which is all about a distance between the middle of a circle and an edge. You require these measurements to find the size of a given cylinder, and you already know how to calculate the surface area of a cylinder. What is it? Remember that the surface area of any solid object is all about a measure of its total area that its surface occupies.
