Hey im trying to compute the volume of the region under the plane z=7 x + 4 y + 34 and over the region in the xy -plane bounded by the circle x^2+y^2=4 y.(adsbygoogle = window.adsbygoogle || []).push({});

i cant seem to get it.... like i i know that the circle is x^2+(x-2)^2=4

so 0<r<2 and 0<theta<2pi

this is what i try

double integral of (7x+4y+34) in polar tho... and it doesnt work... wat am i doinig wrong.. and i cant seem to center the circle... any help would be much appreciated...
