Q26 of 78 Page 13

Mark the correct alternative in the following:

A cylindrical tank of radius 10 m is being filled with wheat at the rate of 314 cubic metre per hour. Then the depth of the wheat is increasing at the rate of


The volume of a cylinder, of radius r and height h, is defined as

V(r,h)=πr2h


Given that r=10m, we get


V(h)=π×102×h=100πh – (1)


Given that , we have to calculate


Differentiating (1) with respect to t, we get



Substituting values and using π=3.14, we get



⇒
