Question

in a cylinder radius is doubled and height is halved then its corved surface area will get​

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.

Answer 2

Answer:

the CSA remains the same

Step-by-step explanation:

Let the radius of cylinder be : r

Let the radius of cylinder be : rand height : h

so original CSA :- 2pie.r.h

when radius is doubled and height is halved the

New CSA= 2pie (2r) (h/2)

=2pie.r.h

therefore new CSA =original CSA therefore CSA remains same hope it helped
