Question

in a cylinder in a radius is doubled and height is haveled curved surface area will be​

Answer 1

Step 1: Using the given condition find Curved Surface Area of Cylinder

Let us assume r is the radius of cylinder and h is the height of cylinder

∴Curved surface area of cylinder is 2πrh

If the radius is doubled and height is halved

⇒R=2r,H= h/2

∴Curved surface area of the cylinder =2πRH

2π(2r)(h/2)

2πrh

Therefore, the curved surface area of the cylinder will be the same.

Answer 2

Step-by-step explanation:

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.
