The base areas quadruple and the curved surface doubles.
The volume of the cylinder would be doubled.
since the volume of a right cylinder is height x area of base, the area of the baseis Pi * r^2 (r is radius which is 1/2 of diameter), so the area of the base did notchange, while the height is doubled so the volume is doubled.
It doubles The volume of a cylinder height times diameter squared times 3.14
The circumference is doubled or tripled, respectively.
If the altitude is not changed, the area would be doubled.
The volume of the cylinder would be doubled.

The diameter of a circle is doubled if the circumference is doubled.
It doubles The volume of a cylinder height times diameter squared times 3.14
The surface area of the 'wall' doubles, but the base areas remain the same.
The circumference is doubled or tripled, respectively.
When the diameter is doubled, perhaps? Then the area is 4 x larger.
If the altitude is not changed, the area would be doubled.
The volume is doubled.
Volume doubles
Volume doubles
If you double the circumference. the diameter like wise would double.
