Order is 1243
1st red square(1) is placed in top left of the big square.
2nd light green square(2) is placed in top right of the big square.
3rd dark green square(4) is placed in bottom right of the big square.
4th yellow square(3) is placed in bottom left of the big square.

A circle circumscribed 5 squares with side length 1, as shown below. (The squares are in a 2×2 grid and one circle on the right middle). What is the radius of the circle?

A circular cone with height 24 and radius 6 is placed on its circular face on a table. It is then cut by a horizontal plane, which is parallel to the circular base and passes through the midpoint of the height. The volume of the lower part of the cone can be written as A*PI.

A plane was returning from the Olympic Games with five athletes who placed first through fifth in an event. They made the following statements:
A: "I was not the last"
B: "C was the third"
C: "A was behind E"
D: "E was second"
E: "D was not the first."
On account of modesty or for some other reason, the gold and silver medallists lied. The three worst athletes told the truth.
What order did they all place in?
