    Let the radius of circle = $$r$$ cm Area of circle = $$pi r^2 = 616$$ => $$frac{22}{7} imes (r)^2 = 616$$ => $$(r)^2 = frac{616 imes 7}{22} = 196$$ => $$r = sqrt{196} = 14$$ cm $$ herefore$$ Circumference of circle = $$2 pi r$$ = $$2 imes frac{22}{7} imes 14$$ = $$44 imes 2 = 88$$ cm => Ans - (B)
