    The cheesecake has 12 slices.

    Step-by-step explanation:

    In order to solve this problem we first need to calculate the total area of the cheesecake, since it's a circle it's area is given by:

    cheesecake area = pi*r²

    cheesecake area = pi * (10/2) ² = pi * (5) ²

    cheesecake area = 25*pi square inches

    There seems to be a typing error on the slice area, from google I found that the correct area is "25pi/12" square inches per slice. Therefore the number of slices must be the division of the cheesecake total area by the area of each slice:

    number of slices = 25*pi / (25*pi/12)

    number of slices = 12

    The cheesecake has 12 slices.
