Unformatted text preview: Question. Let ∂R be the positively oriented piecewise smooth surface that encloses the region R . Let r ( x, y, z ) = x i + y j + z k , the socalled position vector . a . Use the Divergence theorem to show that the volume of R is given by V ( R ) = 1 3 R ∂R r · n dA . b . Use the right side of part (a) to Fnd the volume of a sphere of radius a , given that the surface area of the sphere is 4 πa 2 . 1...
