Ruby program to calculate the volume and area of the Cylinder

Program/Source Code:

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

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

radius=0.0;
height=0.0;
volume=0.0;
area  =0.0;

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

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

volume = 3.14 * radius * radius * height;
area   = 2.0 * 3.14 * radius * (radius + height);
    
print "Volume of Cylinder is: ",volume;
print "\nArea of Cylinder is: ",area;

Output:

Enter radius: 6
Enter height: 2.34
Volume of Cylinder is: 264.51359999999994
Area of Cylinder is: 314.2512

Explanation:

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