Question

What is the arc length of a quarter circle with a radius of 6 inches?

Answer 1

9.42 inches

Explanation:

the cercle length is : 2π×r = 2×3.14 ×6=37.68 inches

the arc length of a quarter circle is : 37.68/4 =9.42 inches

Answer 2

Arc length will be equal to the perimeter divided by 4 since we are talking about quarter circle.

`2\pi r/4=\pi r/2=6\pi/2\approx\boxed{9.42}`

Hope this helps.
