Ruby program to calculate the volume and area of Sphere

Last Updated : December 15, 2025

Problem Solution

In this program, we will read the radius of Sphere from the user. Then we will calculate the volume and surface area of the Sphere and print the result.

Program/Source Code

The source code to calculate the volume and area of Sphere is given below. The given program is compiled and executed successfully.

# Ruby program to calculate the 
# volume and area of Sphere

radius=0.0;

volume=0.0;
area  =0.0;

print "Enter radius: ";
radius = gets.chomp.to_f;  

volume = (4.0 / 3.0) * (3.14) * radius* radius* radius;
area = 4.0 * (3.14) * radius* radius;

print "Volume of Sphere is: ",volume;
print "\nArea of Sphere is: ",area;

Output

Enter radius: 4.56
Volume of Sphere is: 396.9747763199999
Area of Sphere is: 261.16761599999995

Explanation

In the above program, we created three variables radius, volume, and area, that are initialized with 0.0. Then we read the radius of Sphere from the user and calculated the surface area and volume of Sphere using the standard formula. After that, we printed the result.
