The centroidal moment of inertia of a circle having a diameter value of 20 cm is: O a. 7.853*10 5 m4 O b. 7,853*10-2 m O c. 7.853*10 4 m O d. 7.853*103 m4 ho a For a submerged tilted plate in a fluid reservoir, the average pressure can be expressed as: O a. Pe=Po + pg (s + b/2)ab O b. Pe=Po + pgh, O c. Pe=Po + pg (s + b/2) coso O d. Pe=Po + pg (s + b/2) Je
