Okay I managed to figure it out after reading: http://mathinsight.org/double_integral_volume My boundaries were correct but the equation I was integrating was not. It explained that the integral equation is not f(x,y) but f(x,y) - g(x,y), in my case g(x,y) being the "other surface" or z = 5 As...

Thanks for the response! However, that is the answer I entered into Webwork but it states it is incorrect.

Homework Statement Set up the double integral in rectangular coordinates for calculating the volume. The solid is created by the equation Homework Equations Fubini's Thereom ∫R∫f(x,y)dA = ∫ab∫f(x,y)dydxThe Attempt at a Solution The shape created by Z = 30 - x2 - y2 is 3d parabola facing...

Homework Statement At time t=0, a proton is a distance of 0.360 meters from a very large insulating sheet of charge and is moving parallel to the sheet with speed 990 meters/second . The sheet has uniform surface charge density 2.34 * 10^-9 (C/M^2). What is the speed of the proton at...
