 Question 9125: A tuna can has a diameter of about 8cm. and a height of about 3 cm.what is the volume of the tuna can? (the answers are.......150.72cm, 75.36cm, 602.93cm,or none of these) P.S. each of the problems have a little 3 at the top right corner I just couldn't find a key for that button.Answer by longjonsilver(2297)   (Show Source): You can put this solution on YOUR website!a length has unit such as cm or inch or km or mile or yard or meter. An area is 2 lengths multiplied together, producing a 2-D space... their units echo this multiplication and an area is quoted as cm^2 or inch^2 or km^2 etc A volume is 3 lengths multiplied together, producing a 3-D space... their units, again, exho this, so that a volume would have units of cm^3 or inch^3 or km^3 etc. the can is a regular shape...a cylinder. The volume of ANY regulat shape is given by the formula (cross-sectional area)*(length) Now a cylinder (... the can) has a cross-section of a circle, whose are is where r is the radius. so the volume of the can = So, put the values in, from the question volume = ...the diameter is 8cm, so the radius is 4cm volume = volume = work this out on your calculator. Whatever your answer, you have just calculated a volume, whose 3 "lengths" were all cm, so its unit is . jon.
