first take 4 common frm 2nd eq then subtract both equation x n y will b canceled n z will be = to 4
anonymous
  • anonymous
Okay.Then?
anonymous
  • anonymous
then by comparin method find the value of x n put it in any of equ then y will automatically come

Okay. Let's say I got the value of x, y and z. How will I calculate the volume? I am a bit rusty on triple integrals.

  • anonymous
hmm thts pity difficult :P
anonymous
  • anonymous
multiply all the values didnt u get it?
anonymous
  • anonymous
Well the process I saw online was very difficult and it required a lot more effort. Just multiplication won't help.

that would be the projection on the x-y plane?
anonymous
  • anonymous
Okay.
anonymous
  • anonymous
so now try elimination one of x/y and write it interms of z and the other var
anonymous
  • anonymous
i mean y=root(z-x**2)

|dw:1359821411153:dw| i hope u know how to find the area of the shaded part? i mean in 2-d? extend it to 3-d adding a dz
anonymous
  • anonymous
fine let's make a guess.............state ur options i m in no mood to solve it either
anonymous
  • anonymous
2pi,8pi,6pi and 35/4
anonymous
  • anonymous
dose are the options... what do u think wud be a good gess
anonymous
  • anonymous
consider two circles x**2 + y**2=4 and x**2+y**2=1 what would be the area b/n them?
anonymous
  • anonymous
radius:2 and 1
anonymous
  • anonymous
4pi-pi? 3pi?
anonymous
  • anonymous
so area=3
anonymous
  • anonymous
times 4 and we get 12pi
anonymous
  • anonymous
nope now it's gone 3d multiply it with 4 #height ok? now it's 12 pi now approximate it to be a cone now wat's the volume of a cone?
anonymous
  • anonymous
owwww i didnt think of that..
anonymous
  • anonymous
4/3 * 12 * pi =8*pi ?
anonymous
  • anonymous
1/3(pi)(r^2)(h)
anonymous
  • anonymous
now find the closest answer
anonymous
  • anonymous
8pi
anonymous
  • anonymous
noo sorry it's 1/3 * 12 *pi 4pi now wat's the closest?
anonymous
  • anonymous
idk deres 2pi and 6pi and 8pi... i gess 2pi then
anonymous
  • anonymous
yup cone obviously has a larger volume :P guess that's it @shubhanknigam
anonymous
  • anonymous
Thank you both of you, Tushara and Avinash. You were a big help. Guess I can sleep now.
