Question

How To Find Tsa Of Cylinder

Answer 1

Answer:

πr(r+h)

Step-by-step explanation:

use this formula

Answer 2

AnsweR:

To find the total surface area or TSA of a cylinder, we obviously need to know the formula for it.

So, Let's derive its formula so that we can easily remember it and use whenever required.

In a cylinder we have two circles one above and one below. With that we have a certain length of height.

Observe the photo attached for the diagram.

We know that the formula for the area of circle is: πr².

Here, we have two circles.

So, the area would be 2πr².

Then, we have a certain length of height between the two circles.

The area of that portion of the cylinder will be: 2πrh.

So, the area of whole cylinder will be:

➜ 2πr²+2πrh

➜ 2πr(r+h)
