We have the volume of a hemisphere and the volume of a cylinder

 

The hemisphere has a radius of   10m / 2   = 5m

And its volume  =  (2/3) * pi (radius)^3  =  (2/3) * pi  (5)^3   =  (250/3) pi m^3

 

The cylinder has a radius of 5 and a height  of  25m

Its volume is   pi (radius)^2 (height)  =  pi (5)^2 ( 25)  =  625 pi m^3

 

So..... the total volume is

 

pi ( 250/3 + 625) m^3      =    (2125 / 3) pi  m^3
