I need to provide code for this but don't know how :

public class CirclesCalculations public static void main (String[] args)f int radius = 10; double circumference findCircumference (radius); System.out.println("Circumference: "+circumference) double are a0fDisc = fin System.out.println ("Area: "+ area0fDisc) double volumeOfSphere = findVolumeOfSphere (radius); System.out.println ("Volume of sphere:"+ volume0fsphere): dAreaOEDisc(radius); public static double findCircumference (int r) public static double findAreaofDisc (int r) t public static double findVolumeofSphere (int r)i
