Part A: write 2 1/4 as a decimal and a percent. Part B: write 4 as a fraction and a percent. Part C: Write 75% as a fraction and a decimal. Part D: Put these three numbers in order from least to greatest.

Part A: 2.25-225%

Part B: 4/1-400%

Part C: 3/4-.75

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

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
