r > 0 = r is greater than 0
r ≤ 8 = r is less than and equal to 8
0 ≤ r ≤ 8
I might be wrong but im pretty sure the answer is B.
The length of the side = <span>The length of the arc intercepted by the central
<span>angle
</span></span>∴ length = Θ r
where Θ = <span>central<span> angle in radians
and r = radius
∴ </span></span><span>Θ = 70° = 70 * π /180
</span><span>r = 13 in.
∴ </span>length = <span>(70 * π /180) * 13 ≈ 15.88 in.
</span>
You cant how many digits there are behind the decimal, 3, then ask your self which number has 3 zeroes, 1000, so after that you write 888 over 1000, simple. Hope it helped!!
The third option would be the incorrect one
