Frequently asked questions
Use r = ∛(3V ⁄ 4π). A volume of about 904.78 gives a radius of 6.
Volume grows with the cube of the radius, so reversing it to find the radius means taking the cube root.
Double the radius. The calculator shows both from the volume you enter.
It helps size tanks, balls and droplets when you know the volume but need the radius or diameter.
