Answer:
They have both root common .
Answer:
The reasoning here is that the price should be based on the volume.
for a cylinder it's pi * r² * height
for a cone it's 1/3 * pi * r² * height
you'll notice that the formulas are the same, except that the cone is just one third of the cylinders volume.
so a fair price should be 70ct, ignoring packaging of course.
The bracelet is $200 and the watch is $50
4x50=200+50=250
