You need the circumfrence of the flower bed.  
C=diameter x pi.  

C=100in.x pi. pi=3.1415.....  

C= 100 x 3.1415

C=314.15 which is the distance in inches around the flower bed.

Each curved brick is half a foot long, which is 6 inches.  

314.15 divided by 6

= 52.358 bricks.

Answer:

So actually #1 is answer. Thats because if we see last one it doesn't have a right angle but the original does. In the next one the angles dont match.

Therefore the answer to this question is:

<h2><u>#1 is the answer</u></h2>
