Since there is a 1/2 sphere at each end, this is a complete sphere

Sphere volume     v =4/3 pi r^3  =   4/3 pi (5)^3 = 500pi/3  cm^3

 

The cylinder volume =  pi r^2 h = pi 5^2 (30) = 750 pi

 

Added together      750 pi + 500/3 pi = (2750 pi) /3    cm^3                   not rounded.

                                                               ~2880 cm^3    rounded
