If a snowball melts so that its surface area decreases at a rate of 2 cm2/min, find the rate (in cm/min) at which the diameter decreases when the diameter is 8 cm. (Round your answer to three decimal places.) -1 16 X cm/min Enhanced Feedback Please try again. Keep in mind that the surface area of a snowball (sphere) with radius r is A = 47r². Differentiate this equation with respect to time, t, using the dA Chain Rule, to find the equation for the rate at which the area is decreasing, Then, use the values from the exercise to evaluate the rate of change of the radius of the sphere. Have in mind that the diameter is twice the radius. dt --------
