An ellipsoid has radii with lengths of 9 9, 8 8, and 10 10. A portion the size of a hemisphere with a radius of 5 5 is removed form the ellipsoid. What is the remaining volume of the ellipsoid?

=2754.2=2754.2

Explanation:

The Volume of an Ellipsoid with radii =9,8 and 10=9,8and10

=pi/6times=π6×(major-axis)times×(minor axis)times×(vertcal-axis)

=pi/6(2times10)(2times8)(2times9)=π6(2×10)(2×8)(2×9)

=pi/6(20times16times18)=π6(20×16×18)

=960pi=960π

=3016=3016

Volume of an Hemisphere=2/3(pir^3)=23(πr3) where r=5r=5 is the radius
=2/3pi(5)^3=23π(5)3

=2/3pitimes125=23π×125

=83.34pi=83.34π

=261.8=261.8

So the remaining volume of the Ellipsoid

=3016-261.8=3016261.8

=2754.2=2754.2
