Given the values for radius and height of a Cone, write a C program to calculate Surface Area of the Cone.
Page Contents
Surface_Area = PI * radius * (radius + sqrt(height * height + radius * radius ));
where PI is approximately equal to 3.14
Note: sqrt() is a builtin method present in math.h header file.
