Anthony has a sink that is shaped like a half-sphere. The sink has a volume of 2000/3 π inches . One day, his sink clogged. He has to use one of two cylindrical cups to scoop the water out of the sink. The sink is completely full when Anthony begins scooping.

One cup has a diameter of 4 inches and a height of 8 inches.

How many cups of water must Anthony scoop put if the sink in order to empty it.

it would rotate about 180 degrees.

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)
