You will get the same result.
Using simulation calculations (ALGB)
If you want to find more than one solution using the same formula or
algebraic equation, you can do this quickly and simply by use of the
simulation calculation.
Example
Find the volume of two cones:
1
with height 10 and radius 8 and
2
with height 8 and radius 9.
