Best ResponseYou've already chosen the best response.2we can write a few equations. the radius of the big circle is 9+x and y+5 so y=x+4 the diameter of the small circle is x + the radius of the big circle or x+x+9 = 2x+9 the radius of the small circle is r= (2x+9)/2 finally we can use pythagoras on the small triangle in the small circle (rx)^2 + y^2 = r^2 that is enough info to solve for the difference in area between the two circles
