Answer 1

What is formula for

Answer 2

\[\int\limits_{}^{}\int\limits_{G}^{}\int\limits_{}^{}f(x,y,z)dxdydz\]
if
\[G = ((x,y,z)\in R ^{3}: (x,y) \in D, z1(x,y)<=z<= z2(x,y))\]
and if
\[G=((x,y,z)\in R ^{3}: z1<=z<=z2, (x,y) \in D(z))\]

Answer 3

work it out by calculating a double integration( using Polar functions) and then a Definite integral--that's the result

Answer 4

you know how to solve the double integration by Polar coordinate system?

Answer 5

x=r*cos(phi)
y=r*sin(phi)

\[\int\limits_{}^{}\int\limits_{}^{}f(r,\phi)*dr*d(\phi)\]

Answer 6
