Please check this image. Is it possible to count the number of drops present?

I can't see the image. Are you sure the link is correct? In general, to find circles, use imfindcircle(). There is a demo in the help:

Measuring the Radius of a Roll of Tape

This example shows how to measure the radius of a roll of tape, which is partially obscured by the tape dispenser. Utilize imfindcircles to accomplish this task

Can you also supply me with your imfindcircle() code so I can run it? Since you're a MATLAB instructor developing a course for your students, why not just use the demos already in MATLAB to illustrate the concepts to your students? Why develop new ones, or ask us to?

See if this example using imfindcircles() helps:
