Find the rate of change of the area of a circle when its radius is 18.0 m and the radius is changing at the rate of 10.1 cm/s?
rate in m2/s =
My attempt....
dA/ dt = Pie R^2 * dr/dt
10.1cm/s = pie (1800cm) * dr/dt
dr/dt = 0.0101/pie 3240 * m^3/m^2
dr/dt = 0.0101/pie 3240 m2/s
Can you confirm...
Thanks
