    The candles were 4.19 inches apart.

    Step-by-step explanation:

    In order to solve this problem we first need to calculate the length of the circle that surrounds the cake. Since it has a diameter of 12 inches, then it's length is given by:

    length = 2*pi*r = 2*pi * (12/2) = 37.68 inches

    Since there were 9 candles and they were distributed across the edge of the cake in equal spaces, then we need to take the length of the circle and divide it by the number of candles. We have:

    space = length / candles = 37.68 / 9 = 4.19 inches

    The candles were 4.19 inches apart.
