An inverted pyramid is being filled with water at a constant rate of 25 cubic centimeters per second. The pyramid, at the top, h
as the shape of a square with sides of length 4 cm, and the height is 12 cm. Find the rate at which the water level is rising when the water level is 4 cm.
Use the x and y values from your point and the h and k from the center to write the equation you need to solve for r. The general form of the equation for a circle is . We will fill in accordingly: . Solve for r to get that
