Select the correct answer.

Answer:

Option D is correct.

Volume=\frac{8}{27}\ cubic\ yard

Step-by-step explanation:

Let V be the volume of hay in each stack

Given:

Length of the each stack is \frac{2}{3}\ yard

And Jay stores hay in cubic stacks on his farm.

The volume of the cone is.

Volume\ of\ cone = (side)^{3}

Now, we substitute value of length of stack in above equation.

V=(\frac{2}{3})^{3}

V=\frac{2^{3}}{3^{3}}

V=\frac{8}{27}\ cubic\ yard

Therefore, the volume of hay in each stack is V=\frac{8}{27}\ cubic\ yard

olasank [31]

check the picture below.


since we know all those interior points are midpoints, then those interior lines are midsegments, recall the midsegment is half the parallel base.

in this case, the green DF || AC, and since AC is 50, DF is half that, 50/2.
