### How to calculate Cylinder radius

• Calculate the radius of a cylinder using height and volume or surface area or lateral surface area, or by using surface area.

PI = π = 3.14159 approximately
h = height
V = volume
A = surface area
AB = base surface area
AL = lateral surface area

r = d ÷ 2

Calculate cylinder radius using height and volume:

r =
 V π x h

Calculate cylinder radius using height and surface area:

r =
 1 2
x
h2 + 2

 A π
-
 h 2

Calculate cylinder radius using base surface area:

r =
 AB π

Calculate cylinder radius using height and lateral surface area:

r =
 AL 2 x π x h

### How to calculate Cylinder height

• Calculate cylinder height using cylinder radius and volume, radius and area, or lateral surface area.

Calculate cylinder height using radius and volume:

h =
 V π x r2

Calculate cylinder height using radius and area:

h =
 A 2 x π x r
- r

Calculate cylinder height using radius and lateral surface area:

h =
 AL 2 x π x r

### How to calculate Cylinder Volume

• Calculate cylinder volume using cylinder radius and height. If we only have the radius and area or radius and lateral area, we can calculate the height of the cylinder then calculate volume.

Calculate cylinder volume using cylinder radius and height:
V = π x r2 x h

### How to calculate Cylinder Diameter

• Calculate cylinder diameter using the radius, or base area. Or by calculating the radius from height and volume, height and area, or height and lateral area.

d = 2 x r

Calculate cylinder diameter using cylinder height and volume:

d = 2 x
 V π x h

Calculate cylinder diameter using height and lateral surface area:

d = 2 x
 AL 2 x π x h

### How to calculate Cylinder Surface Area

• The surface area is calculated using the cylinder radius and height. If we don't have the radius or the height, we can calculate the missing part like the formulas above.

Calculate cylinder area using cylinder radius and height:
A = 2 x π x r x h + 2 x π x r2

### How to calculate Cylinder Base Surface Area

• Calculate base surface area using the cylinder radius, or by getting the radius from diameter, or else formulas.

Calculate cylinder base area using cylinder radius:
AB = π x r2

### How to calculate Cylinder Lateral Surface Area

• Calculate base cylinder lateral surface area using the cylinder radius and height.

Calculate cylinder lateral area using cylinder radius and height:
AL = 2 x π x r x h
