They both have the same effect on the surface area of the pipe, but the radius has more effect on its volume/capacity.

Yes, the radius is half of the diameter, therefore the diameter is twice the radius.

the volume changes as radius squared and linear with height, so tripling radius and double of height gives 3 x 3 x 2 = 18 times more volume

Radius
The surface area of the curved part of a cylinder is pi*r2h, where r is the radius and h is the height. If the height is tripled, the area becomes pi*r2(3h), or 3(pi*r2h). So if the height is tripled, the area of the curved surface is also tripled.
Doubling the radius quadruples the volume.

Yes its height is the same as its radius
As the area of a circle is pi*radius2 the increase in area is a factor of 32. So tripling the radius gives an increase in area by a factor of 9.
Doubling the radius doubles the circumference.
