Derivatives of Transcendental and Implicit Differentiation.Please help me answer, show solution if needed. Thank you

7 1 point A stone is dropped into a still pond. Concentric circular ripples spread out and the radius r of the disturbed region increases at the rate of 17 cm/sec. Answer the following (1). 170 is the given value for (2). The area of a circular ripple is A = *r. (3). Differentiating both sides of the equation in B with respect to time, we obtain A = 2 ( ? ) . What is the missing term/expression inside the parenthesis? [B] (4). The area of the disturbed region is changing at the rate of GM when the radius is 7 cm.
