All the questions step wise which you can see​

Answer 1

Step-by-step explanation:

If radius is halved and height is doubled then volume of cylinder is half than original cylinder

1) for ex. volume of cylinder = 3.14 × 4 ×4×8

here radius is 4 and height is 8

then volume is 401.92

2) If radius is half i.e. 2 and height is double i.e. 16

then volume is 200.96

therefore volume of second cylinder is half of original cylinder
