Abcdefgh is a regular octagon. the minimum degree of rotation by which this octagon can map onto itself is °. it will take increments of that degree of clockwise rotation for a′ (the image of a) to coincide with c.

answer are

step-by-step explanation:

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
