Can't answer, I have no idea
If you would like to solve 16x^2 - 81 = 0, you can calculate this using the following steps:
<span>16x^2 - 81 = 0
</span>(4x - 9) * (4x + 9) = 0
1. 4x - 9 = 0 ... 4x = 9 ... x = 9/4
2. 4x + 9 = 0 ... 4x = - 9 ... x = - 9/4
The correct result would be: <span>x = 9 over 4, x = −9 over 4.</span>

Answer:
Length of arc is 2π
Step-by-step explanation:
Length of arc=¤/360 x 2πr
Where:
¤=angle
r=radius
length of arc=90/360 x 2xπx4
Length of arc=1/4 x 8π
Length of arc=8π ➗ 4
Length of arc=2π
