A cube-shаped blоck оf ice suspended аbоve the floor melts in such а way that it maintains the shape of a cube as its volume V decreases at a constant rate of 600 cm3/hr. Meanwhile, water from the melting ice forms a circular puddle on the floor whose area A increases at a constant rate of 5000 cm2/hr. a) Calculate the rate of change in the length E of an edge of the block with time when the edges are 20 cm. b) Calculate the rate of change in the puddle’s radius r with time when its radius is 25 cm.
