The table shows the cumulative number of minutes Alice practices clarinet for the first part of the school year

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

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1

actually what is a question i don't understand
