66 Dans chaque cas, factoriser. a) y2 - 10y + 25 b) y2 +10y + 25
d) 4x4 - 36
e) 36x2 - 12x +1
c) y? - 49
f) 20 - 5x?

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

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
