    10584 inches of paper

    Step-by-step explanation:

    to find the surface area of a cone the formula you use is A = πr (r+h2+r2) * you need to divide 16 by two to find the radius 16 is the diameter*

    and this subsituted is π8 (8+9 (2) + 8 (2)) and this equals 504 inches and you then multiply by 21 to get enough paper to cover all 21 cones and that equals 10584 inches
