A stone is thrown into a pond causing a circular ripple to move outward from the point of entry. The radius is modeled by the the equation r(t) = 2t + 3, where t' is time in seconds. Find the function giving the area of the circular ripple directly as a function of time '. O T(4t2 + 12t + 9) O { 1(2t +3)}2 O 2 1(2t + 3) O 7?(4t +6)
