An acorn drops from a tree into a pond and creates a ripple with a radius that increases at a rate of 10 cm/sec. The radius of the ripple can be expressed as the function R(t) = 10t, where t represents time in seconds. The area of the circle made by ripple can be expressed as the function A(r) = πr2 , where r represents the radius in centimeters. Which function can be used to determine the area of the ripple as a function of time?
