Cut the circular cake in 8 in 3 cuts

1. Make 2 cuts vertical and horizontal and cut 3rd one from center along complete area so we have 4 pieces dived by 2 i.e. 8 but this will be unfair as half the pieces will not have cream so let's find 2nd way out

2. Make 2 cuts vertical and horizontal now stack the 4 pieces 1 on each other and cut along again you will have 8 pieces in all.
