Aran moved a cone-shaped pile of sand that had a height of 4 ft and a radius of 3.2 ft. he used all of the sand to fill a cylindrical pit with a radius of 6 ft.
how high did the sand reach in the pit? use 3.14 to approximate pi and round your answer to one decimal place.
ft
i understand the first part i just need with the second part. the first is 42.87(v=cone) i need finding the height of the cylinder.

Which sum or difference identity would you use to verify that cos (180° - ∅) = -cos ∅? a. sin (α -β) = sin α cos β – cos α sin β b. cos (α -β) = cos α cos β – sin α sin β c. cos (α -β) = cos α cos β + sin α sin β d. sin (α + β) = sin α cos β + cos α sin β

What is the equation of this graphed line? enter your answer in slope-intercept form in the box.

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
