#=492.2#

The Volume of an Ellipsoid with radii #=4,9 and 5#

#=pi/6times#(major-axis)#times#(minor axis)#times#(vertcal-axis)

#=pi/6(2times9)(2times4)(2times5)#

#=pi/6(18times8times10)#

#=240pi#

#=754#

Volume of an Hemisphere#=2/3(pir^3)# where #r=5# is the radius
#=2/3pi(5)^3#

#=2/3pitimes125#

#=(250pi)/3#

#=261.8#

So the remaining volume of the Ellipsoid

#=754-261.8#

#=492.2#
