<h3>Answer:</h3>

arc length = 3π/4 cm

<h3>Explanation:</h3>

The appropriate relations are ...

... A = πr² . . . . area of a circle

so ...

... r = √(A/π)

and

... s = rθ . . . . . arc length

___

Combining these, we have

... s = θ√(A/π)

Filling in your numbers gives ...

... s = (π/4)√((9π cm²)/π)

... s = 3π/4 cm

Well you are trying to find x, so you would divide 5/8 by itself and on the other side.

(5/8x / 5/8) = (10 / 5/8)

x=16

Hope this helps!
