A grain silo is built from two right circular cones and a right circular cylinder with internal measurements represented by the figure above. Of the following, which is closest to the volume of the grain silo, in cubic feet?
Volume of the cone: 1/3 of area of the circle * the height (1/3)π5²*5=(125/3)π volume of the cylinder: area of the circle *the height: π5²*10=250π add up: (125/3)π+(125/3)π+250π≈1047.2 D is the correct answer
