Hi please help me with these questions

44 . For positive orientation of the given surface s, the Flux OF the given vector Field across this Surface is equal to the divergence of the Vector field through the solid region B. That is, A . TRUE B . FALSE 45 . The Volume intergial can be iterated as an inner intergrail over the variable z with limits of intergration from the paraboloid 2 = " ? ty ? to the plane , Z = 9 , followed by a double intergral over the planar region O that is a circular disk of radio's 3 with it's Centre at the origin , in other words expressed in polar coordinates A . TRUE B . FALSE ? ? ? 46. The Flux of the given vector Field across the Surface S equals 243 TT ugls. 2 A . TRUE B . FALSE
