A cylindrical tank of radius 10m 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 (a) 1 m/hr (b) 0.1 m/hr (c) 1.1 m/h (d) 0.5 m/hr

Explanation

Let r be the radius of the cylinder. Then, volume (V) of the cylinder is given by,



`V=pi(radius)^2times height`



`=pi(10)^2h=100pih`
