Answer:
The daughter is 36 years old and the son is 12 years old.
Step-by-step explanation:
180 degrees is (-a, -b) and 360 is (a, b). 360 degrees doesn't change since it is a full rotation or a full circle. Also this is for a counterclockwise rotation. If you want to do a clockwise rotation follow these formulas: 90 = (b, -a); 180 = (-a, -b); 270 = (-b, a); 360 = (a, b)

Step-by-step explanation:
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.
