Find the moment of inertia if 4 balls were connected by weightless rods?

Question

If balls were lying on a chart they would be positioned at

Ball 1 (-2.5 m, -1.5 m) mass = 1 kg (1 & 2 are 3 m apart)
Ball 2 (-2.5 m, 1.5 m) mass = 2 kg (2 & 3 are 5 m apart)
Ball 3 (1.5 m, 2.5 m) mass = 3 kg (3 & 4 are 3 m apart)
Ball 4 (-1.5 m, 2.5 m) mass = 4 kg (4 & 1 are 5 m apart)

rectangular system is centered on chart with Origin being (0,0)

What is the moment of inertia of the x axis?
What is the moment of inertia of the y axis?
What is the moment of inertia of the z axis? (the axis through the origin and perpendicular to the page

Answer 1

Have you ever heard of Parallel Axis Theo-
rem (Steiner's Theorem)?

You still must know moments of inertia for each ball unless you assume they are made of the same material as a neutron star and unless it is so what are their diameter?

Izz=I1 + m1R1^2 +I2 + m2R2^2+I3 + m3R3^2+I4 + m4R4^2
Similarly for Ixx, and Iyy

Gee almost forgot.
R is the distance from the center of gravity of the individual mass to the axis about which you want to find the moment of inertia.
