do you can drawing it please ?

OpenStudy (amy0799):

http://prntscr.com/a5qd5f

jhonyy9 (jhonyy9):

ok so now where is the line of x=6 because you need bounding the graph abouth this line of x=6 and hence in this way will get the needed solid - hope you understand me

OpenStudy (amy0799):

I don't understand what you are asking...

OpenStudy (amy0799):

jhonyy9 (jhonyy9):

than you read the text of your exercise there you have wrote that this graph you need bounding about the line x=6 - yes ?

OpenStudy (amy0799):

I just posted the new graph

jhonyy9 (jhonyy9):

ok. i see it now - so do you can imagine what solid will get after you will bound this graph of the equation about this line x=6 ?

OpenStudy (amy0799):

a triangle

jhonyy9 (jhonyy9):

yes but this triangle you need bounding about this line x=6 - so what will get ? do you can imagine this corp of solid ?

jhonyy9 (jhonyy9):

|dw:1455982564852:dw|

jhonyy9 (jhonyy9):

so amy imagine this solid like a cilinder without this triangular part what we can considering a con - yes ?

OpenStudy (amy0799):

yes

jhonyy9 (jhonyy9):

so how you think how will can getting the volume of this corp exactly ?

OpenStudy (amy0799):

split the integrals One going from 0-4 The other going from 4-6

jhonyy9 (jhonyy9):

ok so from the first one what will get ? and from the second so what will get ?

jhonyy9 (jhonyy9):

so this a way but i have imagined that i can calculi this volume of this corp very easy than i calculi the volum of this cilinder and from this volum of cilinder subtract the volum of this cone - how you think what is the more easy way ?

OpenStudy (amy0799):

umm I don't know. Whichever way you think is easier

jhonyy9 (jhonyy9):

how you think can we makeing an experiens you calculi the way what you have imagined and i will calculi how i have imagined - and at the end we will compare the results - ok. ?

jhonyy9 (jhonyy9):

but please post your calculi here - ok ?

jhonyy9 (jhonyy9):

volum of cylinder = area of base *height V = pir^2 *h V=3,14*6^2 *6 V= 678,24 unit cubed

jhonyy9 (jhonyy9):

volum of con = area of base *height /3 V=pi*r^2 *h/3 V=3,14*6^2 *6/3 V=226,08 unit cubed

OpenStudy (amy0799):

http://prntscr.com/a5qxlb

jhonyy9 (jhonyy9):

volum solid resulted = volum cylinder - volum cone V_sr. = 678,24 - 226,08 V_sr. = 452,16 unit cubed

jhonyy9 (jhonyy9):

ok but this 192*3,14 = 602,88 unit cubed so how you see it too there are samthing difference - yes ? now the question what way is the right way and what is the right result of volum ?

jhonyy9 (jhonyy9):

how you think we ask one somebody helper who is online and can deciding the right way and result - ok ?

jhonyy9 (jhonyy9):

@Zeronknight because you are here - so what is your opinion about ? please

jhonyy9 (jhonyy9):

@pooja195 - please your opinion about these - thank you very much

OpenStudy (amy0799):

your answer is not right because i submitted that answer and it was wrong. My answer is too big I think

jhonyy9 (jhonyy9):

amy your answer is too big because i have checked now your calculi and you have assimed these volum but you need subtract the volum of cone from volum of cylinder ok. ? please try it so

OpenStudy (amy0799):

I don't think you're suppose to do that. You're suppose to solve this by the disc/washer method

jhonyy9 (jhonyy9):

sorry but i dont know this method - how is it ?

OpenStudy (amy0799):

oh, then you can't really help me with it then

jhonyy9 (jhonyy9):

sorry - try somebody else helper please mathmale for example or nesha or who are online

OpenStudy (amy0799):

@ParthKohli @Michele_Laino @mathmale @zepdrix

jhonyy9 (jhonyy9):

@mathmale please here
