Find x. I drew a circle deplicting radius x-2. I solved for x with A= 169pi cm power 2 x= sq root 169 + 2 x = 13 + 2 x = 15 Did I do this correctly? Thank for you timeAnswer by stanbon(57328)   (Show Source): You can put this solution on YOUR website!A circle witht the radius x-2 produces an area of 169pi cm^2 2. Find x. ---------------------- r = x-2 cm -------------- Area = (pi)(x-2)^2 169pi = pi(x-2)^2 (x-2)^2 = 169 ----------- x-2 = 13 or x-2 = -13 Positive solution: radius = 13 cm ==================== Cheers, Stan H.
