Volume of the cone:
V=r^2πx/3
3πx^3=r^2πx/3
Multiply by 3 and divide by π:
9x^3=r^2x
Divide by x:
9x^2=r^2
r=3x

Yes it can. It doesn't have to be, but it can be without too much trouble.

In fact, ALL rhombuses are quadrilaterals.

Let p = points. 0 -6(3) + 4 - 2 = p. Simplify multiplication to get -18 + 4 - 2. -18 + 4 = -14 - 2 = -16.
