1.Find the volume of a cube whose sides each measure 3.9. Round answer to the nearest tenth
2.Find the volume of an ellipsoid with a semimajor axis of length 9 and the first semiminor axis has length of 5 while the second semiminor axis has length of 4.5. Use ð = 3.14 and round your answer to the nearest tenth.
3. The volume of a cube is 3,944.312 cm3. Find the length of each side. Round your answer to the nearest tenth
4. Find the volume of a cylinder whose height is 5 in and whose radius of the base is 3.2 in.

1. V = (3.9)^3 = 59.3
2.
3. V = 3944.312cm^3.
L = crt(3944.312 = 15.8cm.
4. V = pi*r^2h = 3.14*(3.2)^2*5 = 160.8in^3.
