1.	Find the distance covered by the particles in the following figures, and while a particle travels from A to B as shown by the arrows
Answer» Solution :ACTUAL LENGTH of the PATH traversed is = `AC+CD+BD` Actual length of thepath traversed `=AC+CD +DBrArr a+(pia)/2+a` `[:. "Circumference of a Circle" =`pixx"DIAMETER"]=2a=(pia)/2`
