By calculating the areas of circles with diameters 6 and 4 and comparing those: pi3^2=pi9 pi2^2=pi4 pi9/pi4=9/4=2.25 So the 6 inch pipe holds 2.25 times as much as the 4 inch pipe.
In Euclidean planar geometry, not unless they're collinear, in which case they intersect an infinite number of times. In other types of geometry ... maybe.
It depends on how many lines intersect. An infinite amount.
I want to say 2, once at each corner
Coplanar lines can intersect an infinite amount of times.
STP diameters are restricted by convergence times.

To intersect means to come together. Here are some sentences.Your path and mine will intersect sometime in the future.Those two roads intersect at the foot of the mountain.Their fates intersect.The north-south highway intersected the east-west highway on the western edge of Toronto.The trains run at different times because their tracks intersect.
parallel lines never intersect.
No, they're two different avenues. They do intersect at one point, though: Times Square.
no yes of course. they can intersect infinite times when they coincide

To determine an earthquake's epicenter, seismologists typically need data from at least three seismic stations. By comparing the arrival times of the seismic waves at each station, they can triangulate the epicenter's location. Additional seismic stations can improve accuracy.
Their circumferences are in the same ratio as their diameters.
9 because 1 times 3 equals 3 and 2 times 3 equals 6.
