The rate of change of volume with radius for a cylinder of radius 5.5 in. and height 20 in. is 690.8. Verify the above statement by differentiation and also by actual calculation of the volumes for a change of radius form 5.4 to 5.6 in.
@mathsuse,
The volume of a cylinder is given by Pi x Rsquared x h
The rate of change ov volume with radius is giveen by 2 x Pi x R x h
