AP Review 2: Question 6 Patricia Martinez

- A container has the shape of an open right circular cone. The height of the container is 10cm and the diameter of hte opening is 10cm. Water in the container is evaporating so that its depth //h// is changing at the constant rate of -3/10 cm/hr. (Note: V= 1/3π//r// 2 h)

a) Find the volume V of water in the container when h = 5cm. Indicate units of measure. b) Find the rate of change of the volume of the water in the container, with respect to time, when h=5cm. Indicate units of measure. c) Show that the rate of change of the volume of water in the container due to evaporation is directly proportional to the exposed surface area of the water. What is the constant of proportionality?



Sorry if it's kind of hard to read. :/

Looks great; checked by Emily Clark
