#color(purple)("Remaining volume of ellipsoid " V_r ~~ 2764.6 " cubic umits"#

#"Vol. of ellipsoid " = V_e = (4/3) pi a * b * c#

#"If a = b = c, it becomes a sphere and vol. " = V_s = (4/3) pi r^3#

#"Vol. of hemisphere = V_h = V_s / 2 = (2/3) pi r^3#

#"Given : " a = 8, b = 8, c = 12, r = 6#

#"Remaining vol " V_r = V_e - V_h = (4/3) pi a^2 c - (2/3) pi r^3, a = b#

#V_r = (4/3) * pi * 8^2 * 12 - (2/3) * pi * 6^3#
