Cone problems

we are going to calculate the area and volume of the cone that has the following measurements: g = 15 cm, a = 12 cm, and r = 9 cm. We calculate the area:

If we had a cone to fill with cream, flush, that is, that ice cream does not protrude from the cone; and that cornet had the following dimensions: the radius of the base measures 3 cm; the height of the cornet is 15 cm; and the generatrix of the cornet measures 17 cm, what area of the biscuit has been used in the manufacture of the cornet
