Question 96671: We have word problems that we have to take them and use an equation to figure out the answer. COuld you please help me with the following problem? A storage bin for corn consists of a cylindrical section made of wire mesh, surmounted by a conical tin roof. The height of the roof is one-third the entire height of the structure. If the total volume of the structure is 1400 pi ft^3 and its radius is 10 ft, what is its height?
I have tried to make an equation but im not sure if I am heading in the right direction. I took the formula for the cylinder and added it with the forlmula for the cone and set them equall to 1400 pi. Then I was going to solve for h, but i got stuck right there. Thanks!
