import java.util.Scanner;

public class KboatOverloadPerform

    double perform(double r, double h) {
        double l = Math.sqrt((r * r) + (h * h));
        double csa = Math.PI * r * l;
        return csa;
    }
    
    void perform(int r, int c) {
        for (int i = 1; i <= r; i++) {
            for (int j = 1; j <= c; j++) {
                System.out.print(j + " ");
            }
            System.out.println();
        }
    }
    
    void perform(int m, int n, char ch) {
        if (ch == 'Q') {
            int q = m / n;
            System.out.println("Quotient: " + q);
        } else if (ch == 'R') {
            int r = m % n;
            System.out.println("Remainder: " + r);
        } else {
            System.out.println("Invalid Character!");
        }
    }
    
    public static void main(String[] args) {
        KboatOverloadPerform mo = new KboatOverloadPerform();

// Calculating CSA of a cone
        double csa = mo.perform(3.0, 4.0);
        System.out.println("Curved Surface Area of Cone: " + csa);

// Generating pattern
        mo.perform(4, 5);

// Printing quotient or remainder
        mo.perform(20, 6, 'Q');
        mo.perform(20, 6, 'R');
    }
