What are the dimensions of the silo

Reference no: EM13188167

A grain silo consists of a cylindrical concrete tower with a hemispherical metal dome on top. The metal in the dome costs 1.5 times as much as the concrete (per unit of surface area). If the volume of the silo is 750 m3, what are the dimensions of the silo (radius and height of cylindrical tower) that minimize the cost of the material? Assume the silo has no floor and no flat ceiling under the dome.
