The grain stored inside a cylindrical silo is transferred to a transport container in the shape of a triangular prism. The container's triangular base has side lengths 5.8m, 5.8m, and 8.1m and height 7.2m. The silo has a radius of 5.83m. a) Find the volume of grain that will be removed from the silo if the container is completely filled. b) Find the amount by which the height of grain inside the silo will decrease. Give your answers to an appropriate degree of accuracy. The cylinder has a radius of 3cm and a height of 18cm. Each ball has a radius of 3cm.
