Question

The radius of a cylinder is increasing at the rate of 3 m/s and its height is decreasing at the rate of 4 m/s. The rate of change of volume when the radius is 4 m and height is 6 m, is ____________.

विकल्प

• 80π cu m/s

• 144π cu m/s

• 80 cu m/s

• 64 cu m/s

Answer 1

The radius of a cylinder is increasing at the rate of 3 m/s and its height is decreasing at the rate of 4 m/s. The rate of change of volume when the radius is 4 m and height is 6 m, is 80π cu m/s.
