Method #1 – Circumference from the volume
Calculator
Formula – How to calculate the circumference of a sphere from the volume
Step 1: Calculate the radius
Radius = 3√((3 x Volume) ÷ (4 x π))
Step 2: Calculate the circumference
Circumference = π2r
Example
A sphere has a volume of 10
Radius = 3√((3 x 10) ÷ (4 x π))
Radius = 3√((3 x 10) ÷ (4 x 3.14159))
Radius = 3√(30 ÷ 12.56636)
Radius = 3√(2.38733)
Radius = 3√(2.38733)
Radius = 1.33651
Circumference = π x 2 x 1.33651
Circumference = 3.14159 x 2 x 1.33651
Circumference = 8.39753
Method #2 – Circumference from the surface area
Calculator
Formula – How to calculate the circumference of a sphere from the surface area
Step1: Calculate the radius
Radius = √(Area ÷ 4π)
Step 2: Calculate the circumference
Circumference = π2r
Example
A sphere has a surface area of 10
Radius = √(10 ÷ (4 x 3.14159))
Radius = √(10 ÷ 12.56636)
Radius = √0.795775
Radius = 0.89206
Circumference = π x 2 x 0.89206
Circumference = 3.13159 x 2 x 0.89206
Circumference = 5.60497
Method #3 – Circumference from the radius
Calculator
Formula – How to calculate the circumference of a sphere from the radius
Circumference = π2r
Example
A sphere has a radius of 10
Circumference = π x 2 x 10
Circumference = 3.14159 x 2 x 10
Circumference = 62.8318
Method #4 – Circumference from the diameter
Calculator
Formula – How to calculate the circumference of a sphere from the diameter
Circumference = πd
Example
A sphere has a diameter of 10
Circumference = π x 10
Circumference = 3.14159 x 10
Circumference = 31.4159
