The diameter of the sun is approximately 865,000 miles. The diameter of Earth is approximately 7600 miles. Use the methods in the class Math to calculate the following:

- ? The volume of Earth in cubic miles
- ? The volume of the sun in cubic miles
- ? The ratio of the volume of the sun to the volume of Earth

public class Volumes { public static void main(String args[]) { double sunRad = 865000.0/2.0; // Sun radius in miles is half the diameter double earthRad = 7600.0/2.0; // Earth radius likewise double fourOverThree = 4.0/3.0; // A convenient constant, 4/3 double sunVol = 0; double earthVol = 0; double ratioVol = 0; /* You can declare several variables of the same type in a single statement if you wish, so we could write the definitions as: double sunRad = 865000.0/2.0, earthRad = 7600.0/2.0, double fourOverThree = 4.0/3.0; double sunVol = 0, earthVol = 0, ratioVol = 0; However, except in trivial cases it is better to declare variables in separate statements as this is clearer and reduces the possibility of errors. */ // Find the volumes of earth and sun: earthVol = fourOverThree*Math.PI*Math.pow(earthRad,3); sunVol = fourOverThree*Math.PI*Math.pow(sunRad,3); // Find the ratio of their volumes: ratioVol = sunVol/earthVol; // Output the results: System.out.println("Volume of the earth is " + earthVol + " cubic miles"); System.out.println("Volume of the sun is " + sunVol + " cubic miles"); System.out.println("The sun's volume is " + ratioVol + " times greater than the earth's."); } }

**Output of Above Java Program**

Volume of the earth is 2.2984729611703882E11 cubic miles

Volume of the sun is 3.3888078519931213E17 cubic miles

The sun's volume is 1474373.5990122468 times greater than the earth's.
