It is known that a gas cylinder has a diameter of 35cm and a height of 28cm is the surface area of the gas tank
In this article, we will calculate the surface area of a gas cylinder with a given diameter and height. The surface area of a cylinder is an important parameter in various fields such as physics, engineering, and architecture. It is used to determine the amount of material required to cover the surface of the cylinder.
What is Surface Area?
The surface area of a cylinder is the total area of its surface. It is calculated by adding the areas of the two circular bases and the curved surface area. The formula for the surface area of a cylinder is:
A = 2πr(h + r)
where A is the surface area, π is a mathematical constant approximately equal to 3.14, r is the radius of the cylinder, and h is the height of the cylinder.
Given Values
In this problem, we are given the diameter of the gas cylinder as 35cm and the height as 28cm. We need to calculate the surface area of the cylinder.
Step 1: Calculate the Radius
The radius of the cylinder is half of its diameter. Therefore, we can calculate the radius as:
r = diameter / 2 r = 35cm / 2 r = 17.5cm
Step 2: Calculate the Surface Area
Now that we have the radius, we can calculate the surface area using the formula:
A = 2πr(h + r) A = 2 × 3.14 × 17.5cm × (28cm + 17.5cm) A = 2 × 3.14 × 17.5cm × 45.5cm A = 2 × 3.14 × 795.625cm² A = 4991.875cm²
In this article, we calculated the surface area of a gas cylinder with a given diameter and height. We used the formula for the surface area of a cylinder and substituted the given values to obtain the result. The surface area of the gas cylinder is approximately 4991.875cm².
Importance of Surface Area
The surface area of a cylinder is an important parameter in various fields such as physics, engineering, and architecture. It is used to determine the amount of material required to cover the surface of the cylinder. In addition, the surface area is also used to calculate the heat transfer between the cylinder and its surroundings.
Real-World Applications
The surface area of a cylinder has many real-world applications. For example, in the design of a gas tank, the surface area is used to determine the amount of material required to cover the tank. In addition, the surface area is also used to calculate the heat transfer between the tank and its surroundings.
Limitations
The formula for the surface area of a cylinder assumes that the cylinder is a perfect cylinder with no irregularities. In reality, the cylinder may have irregularities such as dents or scratches, which can affect the surface area. Therefore, the formula may not give an accurate result in such cases.
Future Work
In the future, we can extend this work by calculating the surface area of other shapes such as spheres, cones, and pyramids. We can also investigate the effect of irregularities on the surface area of a cylinder.
