Question:

math question?

calculate the surface area of a silo whose radius is 12 ft and whose height is 42 ft.and how much grain would the silo hold

Answer:

Surface area = p x h + 2B P= perimeter H= height B=base Volume = A x h A= area h= height
(Assume the silo is a cylinder right?) Volume = πr?h SA = 2πr? + 2πrh = 2πr(r+h) Given: r = 12 ft, h = 42 ft Surface area = 2πr(r+h) = 2π(12)(12+42) = 648π ft? How much grain = V = πr?h = π(12)?(42) = 6048 π ft?
