Curved & Total Surface Area of Cylinder Explained Simply | Easy Trick by KK Sir | Math Made Easy

Описание: Curved & Total Surface Area of Cylinder Explained Simply | Easy Trick by Excise Inspector KK Sir | Math Made Easy

In this short, Excise Inspector KK Sir clearly explains the Curved Surface Area (CSA) and Total Surface Area (TSA) of a cylinder in the most simple and practical way. This is one of the most confusing topics for students, but here it’s made crystal clear with real-life examples and easy-to-understand logic.

If you’ve ever got confused between 2πrh and 2πr(h + r), this video is a must-watch!
KK Sir not only explains the formula derivation, but also shows how it actually looks in real life with a practical cylindrical object — making the concept stick in your mind forever.

This concept is very useful for school students (class 8, 9, 10), competitive exam aspirants, and anyone preparing for SSC, RRB, Group Exams, Railways, or State PSCs.
The video helps you visualize how the curved surface area forms a rectangle when opened and how adding top and bottom circles gives the total surface area.

👉 Watch till the end to understand:

What is Curved Surface Area (CSA) of a cylinder?

What is Total Surface Area (TSA) of a cylinder?

Real-life example to remember the formula forever

Simple formula derivation:

CSA = 2πrh

TSA = 2πr(h + r)


Difference between CSA and TSA
