Let’s have a look at how to analyze a cylinder before we go into the surface area. In geometry, a cylindrical tube is a three-dimensional shape having two parallel circular bases and a rounded surface area. Let’s study more about cylinder area in this blog.

Find the Cylinder’s Area

The curved surface area of a cylindrical tube is equal to the sum of the two parallel and consistent round faces.

The entire area and lateral extent of a cylindrical tube will be determined in this short essay.

To calculate the area of a cylinder, you must first find the Base Area (B) and Curved Surface (C) (CSA). As a result, the area or surface of a cylinder is equal to the sum of the base area multiplied by two and the area of the bent surface.

A cylinder’s curved surface area is equivalent to a rectangular form with a length of 2r and a width of h.

Where r is the radius of the circular face and h is the cylinder’s elevation.

The area of a rounded surface = a rectangular shape’s location =l x w = dh

B = Area of a Circle = r2 is the starting point.

The formula for a cylindrical tube’s location

The formula for calculating a cylinder’s total surface area is as follows:

2r2 + 2rh is the total area of a cylinder.

2r2 + 2rh = TSA

2rh is the area of the rounded surface area, and 2r2 is the top and lower circular face area.

We obtain; if we take 2r as a common factor from RHS.

TSA = 2r (h + r) TSA = 2r (h + r) TSA = 2r (h + ……………………………………………………… ( Surface of a cyndrical tube formula).

Let’s look at how to tackle problems with a cylinder’s surface.

Example.

Find the total surface area of a cylinder with a diameter of 5 centimetres and a height of 7 centimetres.

Solution.

According to the formula,

TSA = 2r (h + r); TSA = 2r (h + r); TSA = 2r (h +

2 x 3.14 x 5(7 + 5) = 2 x 3.14 x 5(7 + 5)

as well as = 31.4 x 12.

376.8 cm2 is the area of the area of the area of the area of the area

A cylinder’s lateral area.

The side area of a cylinder is defined as the area of the rounded surface of the cylinder. In simple terms, the side surface area of a cylindrical tube equals the area of a cylinder minus the base and bottom locations (circular surface).

The lateral area of a cylindrical tube can be calculated using this formula.

2rh = 2rh = 2rh = 2rh = 2rh = 2rh

Exercising 5.

Calculate the later surface area of a cylinder with a diameter of 56 centimetres and a height of 20 centimetres.

Option.

Offered.

Because the diameter is 56 centimeters, the radius is r =56/2 = 28 centimeters.

h = 20 cm elevation

By means of the formula.

2rh = 2rh = 2rh = 2rh = 2rh = 2rh

2 x 3.14 x 28 x 20 = 2 x 3.14 x 28 x 20

3516.8 cm2 = 3516.8 cm2

As a result, the cylinder’s lateral area is 3516.8 cm2.
