Answer 2

Help please

Answer 3

are you using calculus?

if so take a strip thickness dx and roll it out and you get a trapezoid as shown in blue



then calculate dM and dM_o for mass and moment and \(\large \bar x = \frac{\int\limits_{0}^{h} dM_o}{\int\limits_{0}^{h} dM}\)

if you're not doing calculus, sorry :(
