in exercises 21-26, find the critical numbers (if any) and the open intervals on which the function is increasing or decreasing.

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

la: it's the lateral area

ba: area of the base

option a

hello there,

to convert kg to pounds and ounces you set up

turn the kg into

8.3/x = 1/2.2

x = 18.26

now convert the pounds into

18.26/x = 1/16

x = 292.16

now that is the answer in ounces.

answer: 18.26 lb; 292.16 oz
