To convert an angle from degrees to radians, multiply by π/180°.
Your angle is
(-280°)*(π/180°) = -14π/9
The appropriate choice is ...
B) (-14π/9)
<span>(-6,0) would be correct </span>
Answer:
Radius: 19 yards
Diameter: 38 yards
Circumference: 119. 32
Step-by-step explanation:
Radius
To find the radius you divide the diameter by 2 because, the diameter is a; a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.
So 38 ÷ 2 = 19
So the radius is 19.
_____________________
Circumference
To find the Circumference you need to do 2·π·19
C=2·π
2·π = 6.28
6.28 · 19 = 119. 32
Circumference is 119. 32
