A. √(0.8^2) + (0.6^2) = √1 = 1 => OK
<span>b.(-2/3,√ 5/3) = √(-2/3)^2 + 5/9) = √(4/9 +5/9) = √1 = 1 => OK
c.(√ 3/2, 1/3) = √(3/4 + 1/9) < 1 => it is inside the unit circle
d.(1,1)
= √(1 + 1) = √2 > 1 => NO. This point is beyond the limits of the unit circle.</span>

Answer:
a = -48
Step-by-step explanation:
Radius of the circle = r = 6.4 cm
Length of the arc = s = 8 cm
Measure of angle formed by the arc = <span>θ = ?
The radius of the circle, arc length and the angle made by the arc at the center of the circle are related by the equation:
s = r</span><span>θ
From here we can find </span><span>θ by:
</span><span>θ = s/r
Using the values, we get:
</span><span>θ = 8/6.4
</span><span>
θ</span><span>= 1.25 radians
Thus the radian measure of the angle </span>θ made by the arc will be 1.25 radians
