=2754.2

Explanation:

The Volume of an Ellipsoid with radii =9,8 and 10

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

=pi/6(2times10)(2times8)(2times9)

=pi/6(20times16times18)

=960pi

=3016

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

=2/3pitimes125

=83.34pi

=261.8

So the remaining volume of the Ellipsoid

=3016-261.8

=2754.2
