Question 3: What is the volume of corn held in this cone-shaped grain silo? 1 point
LuckyWell [14K]

Answer:

<u>4,712 yards.</u>

We can use the formula V=1/3hπr² to figure out what the volume of the cone is.

So using the numbers provided the new equation would be V=1/3(20)π15², which would come out to 4,712 yards.
