I must find the volume within the superficie (that's spherical coordinates).
My attempt : If I understand well they ask me to find the volume of a sphere whose radius is so I should find .
I set .
I found that the integral is worth . The is worth . But I don't think I'm right on this.
I'd like to know if I set up well the integral for the asked volume and if I made an error calculating the 2 first integrals. Thanks.
