Onuo RB 900
A"
ORB 9000r
Oro RB-2700
O R8, 270-07-

first option

Step-by-step explanation:

Reflection over y axis --> A'B'C'

A'B'C' rotation around center B'  90° --> A'' B'C''

or

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
