Question

in a cylinder radius is doubled and height is halved then CSA WILL be​

Answer 1

Answer:

When the radius is doubled and height is halved in a cylinder, its CSA will be the same.

Step-by-step explanation:

We know that,

Radius = r

Height = h

So,

CSA = 2πrh

Now,

According to the Question,

R' = 2r

H' = (h/2)

So,

CSA = 2πR'H'

= 2π(2r)(h/2)

= 2πrh

Hence,

When the radius is doubled and height is halved in a cylinder, its CSA will be the same.

Hope it helped

Answer 2

Answer:

The CSA will remain the same.
