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.

The mean of eight numbers is 40 and the mean of other twelve different numbers is 30. What is the mean of all the twenty numbers
lana [24]

Answer:  34

================================================

Work Shown:

S = sum of the first 8 numbers

S/8 = 40 is the mean of those first 8 numbers

S = 8*40

S = 320 so the first 8 numbers add to this value

-------

R = sum of the 12 remaining values

R/12 = 30

R = 12*30

R = 360 is what the other 12 values add to

-------

R+S = 360+320 = 680  is what all twenty values add to. Divide this by 20 to get the overall average

(R+S)/20 = 680/20 = 34
