Well the only mistakes I see are that

a. main is not returning int which invokes undefined behaviour and anything could happen

b. there is no \n at the end of the printf statement so the program is not required to flush the printed value to the screen.

36.0 is a double constant, a float constant would be 36.0F

sqrt accepts and returns double and %f is the indicator to printf to expect a double (there is no indication to expect a float because float are passed as double by default).
