A glass of water can hold 1/6 of a bottle. How many glasses of water can be filled with 3 1/2 bottles of water

Let w = the glasses of water we need to find.

Change 3_1/2 to 7/2.

1/w = (1/6)/(7/2)

(1/6)w = (7/2)

Divide both sides by 1/6.

w = (7/2) ÷ (1/6)

w = (7/2) • (6/1)

w = (21/1)

w = 21

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
