The ultimate proportions of the silo will be determined by your computations. In order to provide the needed capacity, a relatively short silo would need to be fairly wide. A taller silo, on the other hand, could be rather narrow and still hold the necessary amount of grain. Thus there is an Inverse relationship between'r, the radius, and h, the height of the cylinder. Part A Suppose the cylinder has a radius of r. What would be the surface area of the hemi-spherical dome? The construction cost for the metal dome is estimated at $30 per square foot. Write an expression for the estimated cost of the dome. BIUXX 2 15px A V Surface area of dome = Cost of dome =
