How to solve a changing area of circle with related rates

The video tutorial explains a problem involving ripples forming in circles, where the radius of the outer ripple increases at a rate of 1 foot per second. The teacher emphasizes understanding the question to avoid solving for the wrong material. Given that the radius is 4 feet, the tutorial guides through differentiating the area formula with respect to time to find the rate of change of the disturbed area. The solution involves calculating the derivative of the area with respect to time, resulting in a rate of 8π square feet per second.
