Approximate the change in the volume of a right circular cylinder of fixed radius requals21 cm when its height decreases from hequals12 cm to hequals11.9 cm (upper v left parenthesis h right parenthesis equals pi r squared h).

Using the formula for the volume of a cylinder, it is found that it decreases from 16625 cm³ to 16487 cm³, which is a change of 138 cm³.

The volume of a cylinder of radius r and height h is given by:

In this problem, the radius is of 21 cm, thus .

With a height of 12 cm, that is, , the volume, in cubic centimetres, is given by:

With a height of 11.9 cm, that is, , the volume, in cubic centimetres, is given by:

The volume decreases from 16625 cm³ to 16487 cm³.

The change is of:

no this is a nonlinear negative

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
