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 4.1 feet per second, modeled by the function r(t) = 4.1t. The area of a circular ripple is given by the function A(x) = ?x2, where x is the radius of the circle. Express the area of the ripple as a (composite) function of the number of seconds that have passed since the stone entered the pond.
A. A(r(t)) = 4.1?t2 B. A(r(t)) = 8.2?t2 C. A(r(t)) = 16.81?2t D. A(r(t)) = 16.81?t2
