Andreas93 [3]

Answer:

Step-by-step explanation:

It can never be perfect, but what I see, I think yes, because u didn't rotate it 90 degrees since it's not a right triangle, but u did rotate it where it looks close to 90 degrees, so it does look like its 80 degrees as a rotation. Question, does it not say how to rotate it? Like 80 degrees clockwise, or 80 degrees counterclockwise?

Hope this helped!

Answer: 8 yards

Step-by-step explanation:

The formula for calculate the volume of a cone is:

V=\frac{1}{3}r^2h\pi

Where r is the radius and h is the height.

Given thevolume and the height of the cone, you can solve for the radius, as you can see below:

803.84=\frac{r^2(12)(3.14)}{3}\\803.84=12.56r^2\\r=\sqrt{\frac{803.84}{12.56}}\\r=8yards
