The arc length of a subtending arc on a circle has the formula:
s = r<span>θ
where is the arc length
r is the radius
</span><span>θ is the angle subtended
</span>
So,
θ = s/r = 8π / 4.5 = 16<span>π/9
We multiply it with 180/</span><span>π to convert it to degrees.
</span>(16π/90) (180/π) = 320<span>°</span>
