Radius of circle from volume
WebIn calculus we are looking for instantaneous rates of change. ie what is the rate of change of the area at the very instant that the circle is 3cm in radius. Not the average rate of change for the whole second after. Try your thought experiment again, this time using 1/10 of a second. A₂ = 3.1² · π cm² = 9.61 · π cm².
