"Vol. of ellipsoid " = V_e = (4/3) pi a * b * cVol. of ellipsoid =Ve=(43)πabc

"If a = b = c, it becomes a sphere and vol. " = V_s = (4/3) pi r^3If a = b = c, it becomes a sphere and vol. =Vs=(43)πr3

"Vol. of hemisphere = V_h = V_s / 2 = (2/3) pi r^3Vol.ofhemisphere=Vh=Vs2=(23)πr3

"Given : " a = 8, b = 8, c = 12, r = 6Given : 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 = bRemaining vol Vr=VeVh=(43)πa2c(23)πr3,a=b

V_r = (4/3) * pi * 8^2 * 12 - (2/3) * pi * 6^3Vr=(43)π8212(23)π63
