The surface area of a cylinder formula is given here along with the explanation and definition of the surface area of a cylinder. An example question based on the surface area formula for a cylinder is also given which can help to understand the concept in a better way. Also, check out all the cylinder formula to know more about the TSA, curved area, and volume of a cylinder.
Surface Area of a Cylinder Definition
A solid geometrical structure that has two circular bases and two parallel faces then it is cylinder. The circular base radius is also the radius of the cylinder and the of the parallel faces if considered as the height of the cylinder. The total area occupied by the surface of the cylinder is the surface area of the cylinder. The unit of measurement of the surface area is in square units.
Surface Area of a Cylinder Formula
The Surface Area of a Cylinder Formula is
|Formula for Surface Areas of Cylinders|
|Total Surface Area of a Cylinder||TSA = 2 π r(r+h)|
|Curved Surface Area of a Cylinder||CSA = 2 π r h|
Where r is the radius of the circular base of the cylinder. h is the height of the parallel face of the cylinder
Examples Question Based on Surface Area of a Cylinder
Question 1: What will be the surface of the cylinder with height 10 cm and the diameter of the base is 12 cm.
Given, Height = 10 cm Diameter = 12 cm
According to the formula: $2\pi r(r+h)$
$=2\times 3.14 \times 6(6+10)$
