#~=178#

The Volume of an Ellipsoid with radii #=2,7 and 4#

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

#=pi/6(2times7)(2times2)(2times4)#

#=pi/6(14times4times8)#

#=74.67pi#

#=234.57#

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

#=2/3pi(27)#

#=18pi#

#=56.5#

So the remaining volume of the Ellipsoid

#=234.57-56.5#

#~=178#
