I am getting the following errors when I add the code associated with the "findArea" and "findCircumference":

(57): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
(57): error C2556: 'int Circles::findArea(float)' : overloaded function differs only by return type from 'double Circles::findArea(float)'
(10) : see declaration of 'Circles::findArea'
(57): error C2371: 'Circles::findArea' : redefinition; different basic types
(10) : see declaration of 'Circles::findArea'
(58): error C2064: term does not evaluate to a function taking 1 arguments
(62): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
(62): error C2556: 'int Circles::findCircumference(float)' : overloaded function differs only by return type from 'double Circles::findCircumference(float)'

Ok, I was missing the return type at the function headers, but now I am getting the following:

(58): error C2064: term does not evaluate to a function taking 1 arguments
