potter forms a piece of clay into a cylinder. As she rolls it, the length, L, of the cylinder increases and the radius, r, decreases. If the length of the cylinder is increasing at 0.1 cm/sec, find the rate at which the radius in changing when the radius is 1 cm and the length is 5 cm. (Note: A cylinder with radius r and length L has volume V=pir2L.)
