The first 4 rows of seats at Sunset Playhouse are shown below. The rows behind row C follow alphabetically and numerically in the same way. Sarah was sitting in seat H9, when she realized she should have been sitting in seat J7. Which of the following represents the change that Sarah needed to make to be in her proper seat?

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

plz mark brainliest i took the test
