Not enough information has been given but the volume of a cone is 1/3*pi*radius squared *height and its base area is pi*radius squared
No. To be similar ALL lengths must be in the same ratio. If two cylinders have the same radii, but different heights then the radii have one ratio (1:1) but the heights have a different ratio; thus they are not similar.

It depends on their radii and heights.

If the ratio of the radii is 1:3 then the ratio of volumes is 1:27.
It is 27 : 343.

If the ratio is 2 : 7 then the volumes are in the ratio 8 : 343.
It is 8 : 343.

ratio of volumes is the cube of the ratio of lengths radii (lengths) in ratio 3 : 4 → volume in ratio 3³ : 4³ = 27 : 64
No they have different heights and radii.
Volume of a sphere of radius r: V = 4pi/3 x r3 If the ratio of the radii of two spheres is 23,then the ratio of their volumes will be 233 = 1,2167
