Ответ:
The volume of the cone is shrinking at the rate
cubic inches / min.
Step-by-step explanation:
Formula:
Given that,
The base of a cone is expanding at the rate of 1 in / min while it height is shrinking at the rate 3 in/ min.
i.e
and
The volume of a cone is
Differentiating with respect to t
Now putting
and ![\frac{dh}{dt}= -3 \ in/min](/tpl/images/0600/7589/8fda7.png)
To find the rate of changing volume at the moment when base radius is 30 in and the height is 40 in, we need to put r= 30 in and h=40 in.
The volume of the cone is shrinking at the rate
cubic inches / min.
