class Formulas{ static float CSA(int x,float pi,int r,int h){ return x*pi*r*h; } public static void main(String[]args){ float csa=CSA(2,3.142f,4,5); /*U can convert int to double , float to double but can't convert double to int or double to float directly*/ System.out.println(csa); } }

public class Program { static float CSA(int x,double pi,int r,int h){ return x*(float)pi*r*h;} public static void main(String[]args){ float a = CSA(2,3.142,4,5); System.out.println(a); } }

I cant be certain that my method is the best way to achieve this as precision could be lost due to casting from double to float maby @Gaurav could help with this one 😜
