Hi there Student! Your answer is, a number divided by 7, 7/x, because it describes a  variable when there is no variable. Yet there is 7/x but in writing form it would not work. Hope this helped!

the square root of what number? if you add that, then someone will probably answer the question.

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
