1)  Convert 12 cm-radius to meter:

      cm to meter  ⇒  divide by 100

      12 cm ÷   \frac{1 m}{100cm} = 0.12 m

2)  Radius to diameter of each circular tile:
  
     diameter = 2 (0.12 m)
     diameter = 0.24 

3)  Divide the path length by diameter of a circular tile:
     
     24 m ÷ 0.24 m = 100 

ANSWER:  100 tiles are needed
