}

2 errors

I've come across these 2 errors when trying to compile. Any ideas what i have done wrong to get these errors? i am rather new to java and need some assistances thank you

add datatype for Radius and radius in above method.
Certainly there are many errors in your program:-

• In line 37 and 47 add arguement data type.

  public static double calcCirc(double Radius)//line 37
  public static double calcArea(double radius)//line 47

• Pass radius(arguement) in line 18 and 19 to match method parameter.

       circ = calcCirc(radius );//line 18
      area = calcArea(radius );//line 19
  

• rad seems undefined in the line 44 and line 53.As per example it should be

    circ = 2.0 * Radius * pi;//line 44
      area = pi * rad * rad;//line 53
  

I hope so you have understannd your issues in your program.

thank you, i have seem to get my program to work properly with your help.

It seems that you have already get the right answer, the error lies in that the type of the variables"Radius""radius" were not given.
