Question

The difference between the CSA and TSA of a right circular cylinder is

Answer 1

Answer:

CSA and TSA of Cylinder

Curved surface is the wall of the cylinder & plane surfaces are the ground & the roof, circular in shape ( circle shape) . Area of this curved surface is called the CURVED SURFACE AREAof the cylinder. This curved surface when flattened , it takes the shape of a rectangle

Answer 2

Step-by-step explanation:

csa of cylinder is 2πrh

tsa of cylinder is 2πr(r+h)

in curved surface area we will only one side of the radius ., that means we are not measuring the whole quadrilateral (cylinder).

where as in tsa , we should measure the area of the whole cylinder so we must take the upper radius and also lower radius (though both are same) .

hope this helps you
