The degree of the polynomial is determined by the highest power among the terms. The polynomial  -6x^5+4x^3+3x^2+3x^2+11 has the highest degree of 5, hence A. A. quintic. The standard form of -2x^2(-5x^2+4x^3) through the associative property is B. 10 x^4 -8x^5. The expression in 3,  4/3pier^2h represents the height that is equal to B. t the height of entire bottle.
