A cylinder with surface area 219.91 has a radius of 5 units and a height of 2 units

How to determine the height of the cylinder

From the question, we have the following parameters that can be used in our computation:

Surface area = 219.91

Radius = 5

The surface area of a cylinder is calculated using

SA = 2πr² + 2πrh

Substitute the known values into the equation

2π * 5² + 2π * 5h = 219.91

This gives

157.1 + 31.4h = 219.91

So, we have

31.4h = 219.91 - 157.1

31.4h = 62.8

Divide both sides by 31.4

h = 2

Hence, the height of the cylinder is 2 units
