Solve the problem.A stone is thrown into a pond. A circular ripple is spreading over the pond in such a way that the radius is increasing at the rate of 2.6 feet per second. Find a function, r(t), for the radius in terms of t. Find a function, A(r), for the area of the ripple in terms of r. 
A. (A ? r)(t) = 2.6?t2 B. (A ? r)(t) = 5.2?t2 C. (A ? r)(t) = 6.76?2t D. (A ? r)(t) = 6.76?t2
