The ninth-grade teachers at Lincoln High School are buying ice cream for an end-of-year ice cream social. They estimate the 160 students will eat about 2 scoops of ice cream each. If the average scoop of ice cream is 0.5 cups, how many gallons of ice cream should the teachers buy?

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

they disappear if your absent from to long. i found out that the hard way.

step-by-step explanation:

brainliest lol i just need one more brainliest.
