They both have the same effect on the surface area of the pipe, but the radius has more effect on its volume/capacity.
The volume increases faster. (proportional to the cube of the radius)The surface area increases slower. (proportional to the square of the radius)
The surface area is reduced by a factor 4, the volume by a factor 8.

Doubling the radius quadruples the volume.
The volume of a sphere is proportional to R3 .So doubling the radius causes the volume to increase by a factor of 23 = 8 .
If the radius of a sphere is doubled, the surface area increases by (2)2 = 4 times, and the volume increases by (2)3 = 8 times.
It remains the same or increases in surface area.
If the radius of a sphere is tripled, the surface area increases by (3)2 = 9 times, and the volume increases by (3)3 = 27 times.
The volume increases by a factor of four.
As mass increases It increases the surface temperature , luminosity, and radius.
