What error? You didn't post any output.

now i edit the new coding + output!!

[ciphermagi]

Your prototype for volHemisphere doesn't match the function definition.

[TheMassiveChipmunk]

I am not to sure but in the declaration of

void volHemisphere(double &, double);
the second parameter is not a reference

but in the definition
void volHemisphere(double &sphere, double &h)
the second parameter is a reference

So VS thinks this a new function and not the one you declared. And since it thinks it is a new one it expects to get the definition of the old one.

Hope this helps :)
