Answer:

Step-by-step explanation:
Let r be the radius ( in feet ) of the cone,
So, the diameter of the cone = 2 × radius = 2r feet,
∵ The diameter of the base of the cone is three times the height,
If h represents the height of the cone,
⇒ 2r = 3 × h,
⇒
feet,
∵ Volume of a cone,

Where,
R = radius, H = height,
Thus, the volume of the given cone is,



Differentiating with respect to t ( time )

We have,




Answer:
your answer would be -13.8y
The correct answer is 1 23/24. Hope this helps.

Therefore, the slope of the line is 1/3. In case if you want the equation too.

Therefore, the equation is y=1/3x+2/3
