Answer:
60*pi square inches
Explanation:
We have a cone that originally has 15 * pi square inches of area, now it tells us that it is enlarged by a scale factor of four, to make a cone with the same shape.
In other words, if it was a cone with a circular base, this new cone will also be a circular base, the same happens if it is a square base.
Therefore, taking this into account, the new cone area is
15 * 4 * pi = 60 * pi
That is, the area of the new cone would be 60*pi square inches.
