(3) A rock thrown into a still pond causes a circular ripple. for the given x and y a) If the radius of the ripple is increasing by 2 feet per second, how fast is the area changing when radius is 10 feet? Use A = πR2 and π = 3.14 b) How fast is the circumference of a circular ripple is changing when the radius is 5 feet? Use C = 2πR and π = 3.14
