A cylindrical grain also, with a flat top, is 30 ft tall and has a radius of 12 ft. It is full to the top with shelled corn. If the density of shelled corn averages 45 pound./cubic foot, what does the corn in the silo weight to the nearest pound?

 610,416 lb

Step-by-step explanation:

Volume of a cylinder (V) = π r² · h

                                   V = π (12)² · 30

                                      = 4320 π

Density = Volume x weight

             = 4320 π · 45

             = 194,400 π

             ≈ 610,416

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
