A square of a side length s is inscribed in a circle of radius r.
a) Write the area A of the square as a function of the radius r of the circle.
b) find the instantaneous rate of change of the area A with respect to the radius r of the circle.
c) Evaluate the rate of change of A at r=1 and r=8
d) If r is measured in inches and A is measured in square inches, what units would be appropriate for dA/dr?
