1.) Ripples in a Pond A pebble is dropped into a calm pond, causing ripples in the form of concentric circles, as shown in Figure 2.34. The radius of the outer ripple is increasing at a constant rate of 1 foot per second. When the Russ Bishop/Along radius is 4 feet, at what rate is the total area A of the disturbed water changing? Total area increases as the outer radius increases. Figure 2.34
