MGSE8.G.9 Apply the formulas for the volume of cones, cylinders, and spheres
and use them to solve real-world and mathematical problems. 1 11/29/2017 7.04 Volumes of Composite Figures
Log into your OMS and watch the 60-second math video. Can you think of any other real-world objects
that are composed of multiple 3-d shapes? Imagine a grain silo, the place where farmers store their grain after a harvest. They
are usually a cylinder with a cone roof, and the grain is dropped into the silo at the
very top of the cone. To know how much room farmers have for storing their
harvest, they must calculate the volume of the grain silo. Find the approximate
volume of a silo where the radius is 10 ft, height of the cone part is 10 ft, and height
of the cylinder part is 30 ft. Imagine a grain silo, the place where farmers store their grain after a harvest. They
