ice cream is being put into a cone at a rate of 4 cm3/s. the cone has a radius of 2 cm and a height of 8 cm.
at what rate is the height of ice cream rising when it is half full?
be careful- it is not half full when the height of the ice cream is 4 cm!

0.5052 cm per sec ( approx )

Step-by-step explanation:

∵ The volume of a cone is,

Where,

r = radius,

h = height,

Here, r = 2 and h = 8,

Thus, the volume of the cone is,

When the cone is half filled,

Volume would be,

Now,

Differentiating equation (1) with respect to t ( time )

We have,

answer: 20
