Answer: 13.96 in²
<u>Step-by-step explanation:</u>
d = 2r
16 = 2r
8 = r

180(θ) = 25(π)
θ =
θ = 
A =
r² θ
= 
= 
= 13.96

Answer: 270°, 630°, -450°, -810°
<u>Step-by-step explanation:</u>
positive: -90 + 360 = 270
270 + 360 = 630
negative: -90 - 360 = -450
-450 - 360 = -810

If you subtract another 2π, you will end up with a negative value. The question asks for the smallest positive value.
Step-by-step explanation:
1. convert the equation to its y = mx + b format. remember m is the slope (rise/run) and b is the y-intercept.
2. equation given: x + 2y = -6
bring x over to other side
3. now its looks like 2y = -6 - x
to get y by itself we need to divide by 2
4. now equation looks like y = -6/2 -x/2
we can reduce it so the final equation is
5. y = -1/2x - 3
this is in y=mx+b format. now its much easier to graph
6. the slope is -1/2 and the y-intercept is -3. put a point at (0,-3) and use the slope (-1/2) rise over run to get each point.
7. you move to the left because its negative
