Homework Statement
∫∫ F ⋅ ndτ over the spherical region x^2 + y^2 + z^2 = 25
given F = r^3 r i already converted the cartesian coordinates to spherical in F
Homework Equations
n = r[/B]
The Attempt at a Solution
I know I can plug in F into the equation and then dot it with r to get the following:
∫∫ r^3 dτ
r should be constant at r = 5 so i can take it out of the integral and substitute
5^3∫∫dτ
now how can i solve the ∫∫dτ? I would have to convert dτ into spherical coordinates? Note: the double integral should have a circle on it but I don't know how to add one here. Any help is useful.
