Sagot :

The cubic feet of corn the cylinder silo will hold is 4615.8 ft³.

Volume of a cylinder

  • v = πr²h

where

r = radius

h = height

The grain silo is in the form of a right cylinder. Therefore,

diameter = 14 ft

radius = 14 / 2 = 7 ft

height = 30 ft

The cubic ft of corn that will contain the silo is the volume. Therefore,

v = 3.14 × 7² × 30

v = 3.14 × 49 × 30

v = 4615.8

v = 4615.8 ft³
