The answer to the problem is simply the surface area of the paper cone.
The area of a paper snow cone is define as
A =
π(r)(r + l )
where :
r = d/2 = 3/2 = 1.5 in
l = 6 in
so
A = π(1.5)(1.5 + 6)
A = 35.34 sq in
so 35.34 sq in of paper are needed to make it
Hope my answer would be a great help for you.
