### Related Rates – Cone Problem. Water is leaking out of an inverted conical tank at a rate of 10,000 at the same time water is being pumped into the tank at a constant rate. The tank has a height 6 m and the diameter at the top is 4 m. If the water level is rising at a rate of 20 when the height of the water is 2 m,

Suppose that both the radius r and height h of a circular cone change at a rate of 2 cm/s. How fast is the volume of the cone increasing when r = 10 and h = 20? Hi Barbara, The volume of a cone of radius r cm and height h cm is given by. $\begingroup$ To find the rate of change as the height changes, solve the equation for volume of a cone ($\frac{\pi r^2 h}{3}$) for h, and find the derivative, using the given radius. For the rate of change as the radius changes - same idea. $\endgroup$ – CodyBugstein Nov 11 '12 at 2:46 As a result, the water’s height in the cone h is changing at the rate $\dfrac{dh}{dt}$, which is the quantity we’re after. The inverted cone has a radius of 8 cm at its top, and a full height of 20 cm. The radius of a right circular cone is increasing at a rate of 3 inches per second and its height is decreasing at a rate of 5 inches per second. At what
