The radius of a circle is decreasing at a constant rate of 0.1 centimeter per second. In terms of the circumference C, what is the rate of change of the area of the circle, in square centimeters per second?

A. -(0.2)piC

B. -(0.1)C

C. - {(0.1)C}/(2pi)

D (0.1)^2C

E. (0.1)^2piC

EDIT: i changed answer b from -(0.2)C to -(0.1)C i wrote it wrong.

EDIT: i changed the decreasing at a constant rate of 0.2 to 0.1.
