210/360 = 7/12, meaning the shaded area is 7/12 of the entire circle.
The circle has radius 12 in, so its total area is π (12 in)^2 = 144π in^2.
Then the area of the shaded region is 7/12 of this, or
7/12 * (144 π in^2) = 84π in^2 ≈ 263.89 in^2
Answer:
I hate math too <3
Increasing: [0,1]
Decreasing: (infinity,0] U [1,infinity)
A because the reflection is across the y axis
120 - 4 - 6 = ( that is the process, you ca find the answer)
5,223
Nearest tens: 5,220
Nearest hundreds: 5,200
Nearest thousands: 5,000
