Question

Task 1: Write a function that accepts temperature in degrees Fahrenheit and computes the corresponding value in degrees Celsius (°C). The relation between the two is (TOF 32) Using your function convert 80 0F to Celsius (C)

Answer 1

Task 1 .

import java.util.*;
 
class FahrenheitToCelsius {
  public static void main(String[] args) {
    float temperatue;
    Scanner in = new Scanner(System.in);      
 
    System.out.println("Enter temperatue in Fahrenheit");
    temperatue = in.nextInt();
 
    temperatue = ((temperatue - 32)*5)/9;
 
    System.out.println("Temperatue in Celsius = " + temperatue);
  }
}

Task 2

a)

class Area{

double r;
double v;
double a;
double temp;

public void calcA(){

temp = ((3.14*3.14*r*r)+(9*v*v));
a = math.sqrt(temp)/(r*r);

}

}

class sample {

public staic void main(String[] args){

Area ob = new Area();

ob.r = 5;
ob.v = 10;

ob.caclArea();

}

}

Task 2

B)

class Area{

static double v=10;
double a;
double temp;

public double calcA(double r){

temp = ((3.14*3.14*r*r)+(9*v*v));
a = math.sqrt(temp)/(r*r);

return a;

}

}

class sample {

public staic void main(String[] args){

Area ob = new Area();

double area = ob.caclArea(5);

System.out.println("Area is"+ area);

}

}
