24. A body of water with navigable depth leading to a harbour is called: C. shoal A. fairway B. channel D. significant depth 25. The radius of a sphere is r when the time is t seconds. Find the radius when the rate of change of the surface area and the rate of change of the radius are equal. C. 1/16 A. 1/8K B. 1/4 D. 1/2 26.
