The area of a circle is by multiplied by 1/4, what is the effect on the radius?

 

I got the radius would be multiplied by 1/2 (just thru guess check), but idk how to prove it.

Your "guess"  is correct  !!!

 

Since  the  new area is 1/4 of  what it was......any linear  measure on the  circle  (in this  case, the new radius)  = sqrt (1/4)  =    1/2   of  what it  originally  was,,,,,,,
