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

Thus; 
Answer:
3 + 19 - 11
Step-by-step explanation:
18 - 7 = 12
3 + 19 - 11
3 + 19 = 22
22 - 11 = 11
