Amy baked a circularcake witha diameter of 12inches. She put 9 candles evenly spaced around the edge of the cake. About how far apart were the candles.

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.
