Answer:
Mark point E where the circle intersects segment BC
Step-by-step explanation:
Apparently, Bill is using "technology" to perform the same steps that he would use with compass and straightedge. Those steps involve finding a point equidistant from the rays BD and BC. That is generally done by finding the intersection point(s) of circles centered at D and "E", where "E" is the intersection point of the circle B with segment BC.
Bill's next step is to mark point E, so he can use it as the center of one of the circles just described.
___
<em>Comment on Bill's "technology"</em>
In the technology I would use for this purpose, the next step would be "select the angle bisector tool."
Answer:
you need the formula for the cone , Korc
Step-by-step explanation:
formula for cone = 
*π*
*h
they tell us that the diameter is 8 so r = 4
and that h = 9
volume of cone = *π*
*9
VoC = 150.796
VoC = 150.8 ( to the nearest 10th)
