<span>Inflection points are where the function changes concavity. Since concave up corresponds to a positive second derivative and concave down corresponds to a negative second derivative, then when the function changes from concave up to concave down (or vise versa) the second derivative must equal zero at that point. So the second derivative must equal zero to be an inflection point. But don't get excited yet. You have to make sure that the concavity actually changes at that point.</span>
Answer:
first change 1 gallon into quarts and that will be
4.8038
so 2 quarts = ? cross multiply ans the answer u will get is 9.6076
The volume of a cone is (1/3) that of its similar cylinder.
Thus the volume of the cone B would be:
