Finding the Center of Mass for Jane's Leg Model

[lalahelp]

Homework Statement

Jane is sitting on a chair with her lower leg at a 40.1° angle with respect to the vertical, as shown. You need to develop a computer model of her leg to assist in some medical research. If you assume that her leg can be modeled as two uniform cylinders, one with mass M1 = 21 kg and length L1 = 32 cm and one with mass M2 = 6 kg and length L2 = 52 cm, where is the center of mass of her leg?

I have no clue how to solve this can anyone please explain...
