Find radius values from different measurements using simple mathematical conversion methods.
The radius formula depends on the available measurement. For diameter conversion, radius equals diameter divided by two. The formula is r = d / 2.
For circumference conversion, radius equals circumference divided by two times pi. The formula is r = C / 2π. For area conversion, radius equals square root of area divided by pi.
For sphere volume conversion, radius is calculated using cube root relationships. The formula is r = ∛(3V / 4π). These formulas provide accurate radius calculations.
