Question

I will be forever gratefull and be your fan, if you could anwer my question!

Answer 1

you dont have to... we are glad to help
but where is the question??

Answer 2

how do I solve:
Find the volume of the cone z=sqrt(x^2+y^2) and inside the sphere x^2+y^2+z^2=a^2???

Answer 3

How come your volume of cone doesn't include pi ?

Answer 4

In polar coordinates, z=r.

Answer 5

If it fits inside the sphere, r^2<a^2/2

Answer 6

Since r=z, the volume of an differential disk in the cone is pi z^2 dz.

Answer 7

Integrate from zero to a/sqrt (2) to get the answer.

Answer 8

okay. i will try. thanks alot :)

Answer 9

It might be close to\[\pi \int\limits_{0}^{a/\sqrt{2}}z^2dz=\pi(a/\sqrt{2}) ^{3}/3\]

Answer 10

or not.... Hope I helped.

Answer 11

you did. thanks mate :)
