Mr. Wahman loves to eat ice cream. He especially loves waffle cones, but he can
never get the ice cream shop to make them the way he likes them. He wants cones
which hold as much ice cream as possible, but without ice cream sticking over
the edge of the cone (too messy). He decides to design his own waffle cones. His
waffle iron makes circular waffles, which he can twist into a cone by first
making one cut along a radius. He needs to know what size cone to make.
What are the dimensions of the cone that holds the most ice cream (level to the top)?

Could someone explain & help me with arranging polynomials in a descending order?

1. -2x - x^9 + 14^7 - 3x^3
2. 8m^2n^2 - 4m^3n - 4mn^3
3. 5a^3b^ - 5a^5 - 10a^4b

Does it depend on total number of exponent, numerical coefficient and/or alphabetical arrangement?

Please & thank you!
