Question on Comparison and Checking

Hi everyone,

Using Rule of Engine, how can I compare columns and check if the value is true or false.

For instance I need to check if the calculations for a volume of sphere is correct.

Column A is the Radius

Column B is Pie (3.142)

Column C is the volume of the sphere

Formula: 4/3 Pie Radius ^3

my formula is : if (4/3 Column A^3 Column B) == Column C => True Else False
