Answer: 4
Step-by-step explanation:
A = [tex]\frac{1}{2}[/tex]r²θ
50 = [tex]\frac{1}{2}[/tex](5)²θ
100 = (5)²θ
100 = (25)θ
4 = θ

Answer: 1570.80 cm²
Step-by-step explanation:
A = [tex]\frac{1}{2}[/tex]r²θ
A = [tex]\frac{1}{2}[/tex](100)²[tex](\frac{\pi}{10})[/tex]
A = 500π
A = 1570.80

Answer: 19.63 m²
Step-by-step explanation:
A = [tex]\frac{1}{2}[/tex]r²θ
= [tex]\frac{1}{2}[/tex](5)²[tex](\frac{\pi} {2})[/tex]
= [tex]\frac{25\pi} {4}[/tex]
= 19.63

Answer: 15°
Step-by-step explanation:
[tex]\frac{\pi }{180} = \frac{\pi} {12x}[/tex]
180 = 12x
15 = x

Answer: A
Step-by-step explanation:
Quadrant I: 0° - 90°
Quadrant II: 90° - 180°
Quadrant III: 180° - 270°
Quadrant IV: 270° - 360°
255° is in Quadrant III
