#color(green)(V_r = color(green)(936.5714)# cubic units

Ellipsoid volume #V_e = (4/3) pi a b c#

Given : #a = 14, b= 7, c = 6#

#color(blue)(V_e) = (4/3) pi (14*7*6) = color(blue)(2464)# cubic units

Volume of hemi sphere #V_h = (2/3) pi r^3#

Given #r = 9#

#color(blue)(V_h) = (2/3) pi 9^3 = color(blue)(1527.4286)# cubic units

Remaining volume of ellipsoid

#color(green)(V_r =2464 - 1527.4286 = color(green)(936.5714)# cubic units
