W36x210 as shown in Fig. 1.  
Determine the following section properties of the built-up cross section: 
a. Cross sectional area, A (in2) 
b. The location of the centroids CG-X and CG-Y id of the built up section from the bottom of angle ( this value is given, so you need to check that you get this value) 
c. Moments of  inertia  ICG-X (in4) and ICG-Y (in4) 
d. Section modulus Sx (bot) (in3) and Sx (top) (in3) 
e. Radius of gyration rx (in) and ry (in) 
f. Weight of the built up section, w (lb/ft) (use density of steel = 490 pcf)

g. Surface area of the built-up section, S(ft2/ft)
