When a circular plate of metal is heated in an oven its radius increases at a rate of 0.04cm per min At what rate is the plates area increasing when the radius is 42cm?
We note that the area of a circle is as follows: A = pir2.Taking the derivative with respect to time:dA/dt = 2pi * dr/dtAs r = 42cm and dr/dt = 0.04cm/min,dA/dt = 2*pi*42cm*(1/25)cm/min=84pi/25 cm2/min= approx 10.556 cm2/min
