3. A grain silo in the shape of a cylindrical building with a hemispherical dome roof is to be built on a farm. The cost of the materials is as follows: bricks for the sides cost $15/m², tiles for the roof cost $25/m² and concrete for the floor costs $10/m². If the volume of the silo is 23000 m³, determine a) the dimensions that will minimize the cost to build the silo b) the minimum cost to build the silo (to the nearest cent).
