Hi there!
Usually, the amount of flour varies between different cookie recipe's, but if you're going to make the normal chocolate chip cookie, into a batch of 60, you'd need 4 cups of flour.
So, 4 cups of flour would make your 60 chocolate chip cookies.
Hope this helps! :D

Answer:
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
