Suppose That f(x,y,z)=g(x2+y2+z2)f ( x , y , z ) = g \left( \sqrt { x ^ { 2 } + y ^ { 2 } + z ^ { 2 } } \right)

Question 115

Multiple Choice

Suppose that f(x,y,z) =g(x2+y2+z2) f ( x , y , z ) = g \left( \sqrt { x ^ { 2 } + y ^ { 2 } + z ^ { 2 } } \right) where gg is a function of one variable such that g(3) =4g ( 3 ) = 4
Evaluate Sf(x,y,z) dS\iint _ { S } f ( x , y , z ) d S where SS is the sphere x2+y2+z2=9x ^ { 2 } + y ^ { 2 } + z ^ { 2 } = 9 .
