Question

in a cylinder , radius is double and height is halved ,find the curved surface area​

Answer 1

Answer:

The curved surface area will remain same. So, there is no change in the curved surface area of cylinder . Hence the curved surface area will remain same.

Step-by-step explanation:

Curved surface area of cylinder is 2πrh.

Given, R=2r,H=

2

h

Therefore, curved surface area of the cylinder=2πRH

=2π(2r)(

2

h

)

=2πrh

Answer 2

Answer:

CSA of cylinder=2πrh

here,2π2rh/2 is given

this is same as 2πrh

there is no change in its CSA
