svetoff [14.1K]

Answer:

Step-by-step explanation:

In this case the solution of the integral is

$\int\limits^{2\pi} _0 {} \, d\phi \int\limits^R_0 {\rho}h \, d\rho = [2\pi - 0](\frac{1}{2} )[R^{2} - 0]h = \pi R^{2}h$

because h is a constant, and where the expression

$\int {\rho} \, d\rho = \frac{\rho^{2}}{2}$

was used.

I hope this is usefull for you
