The image above represents a cylinder. To calculate the area of a cylinder requires two essential parameters which are the radius and height of the cylinder.
The formula for computing the area of a cylinder is:
A = 2Ï€rh + 2Ï€r2
Where:
A = Area of a cylinder
r = radius of the cylinder
h = height of the cylinder
Let’s solve an example
Find the area of a cylinder with a radius of 3 cm and a height of 5 cm.
This implies that:
r = radius of the cylinder = 3
h = height of the cylinder = 5
A =Â 2Ï€rh + 2Ï€r2
A = 2(3.142) x 3 x 5 + 2(3.142) x 32
Then, A = 150.82
Therefore, the area of the cylinder is 150.82 cm2.
Calculating the Height of a cylinder when Area and Radius is Given
The formula is h = Â A/ 2Ï€r – r
Where;
A = Area of a cylinder
r =Â radius of the cylinder
h = height of the cylinder
Let’s solve an example:
Find the height of a cylinder with an area of 600 cm² and a radius of 5 cm
This implies that;
A = Area of the cylinder = 600 cm²
r = radius of the cylinder = 5 cm
h =Â A / 2Ï€r – r
h = 600 / 2(3.142)(5) – 5
Then, h = 600 / 31.42 – 5
h = 19.10 – 5
h = 14.10
Therefore, the height of the cylinder is 14.10 cm.
