The number is 90. 20% of 90 of 18, and 90 decreased by 18 is 72.
If we let V', A', and r' represent the rates of change of the volume, area, and radius of the sphere, we can differentiate equations for V and A in terms of r, then eliminate r' to get an equation for A' in terms of V'.
Then, for the given values, the surface area is increasing at the rate ...
... A' = (2/8)·25 ft²/s = 6.25 ft²/s
