sorry,. x^2=98. but what can i do then? thanks.

I mean for z I used 14+x, and r; for r, I used 0 and 1; for theta, i use 0 and 2pi? if those are all correct, how can i get exact number? i should have x in final answer. Thanks

thanks. but i still not understand the range for z, and that function i should use for f(x,y)which be intefrated. thanks.

Homework Statement find the volume between the cone x=√y^2+z^2, and the spherex^2+y^2+z^2=196 Homework Equations The Attempt at a Solution for x=√y^2+z^2, I got x^2=y^2+z^2, and 2x^2=196, x=98, for this, I don't know what i am supposed to do then. Thanks!
