Question

In circle R with mZQRS = 112 and QR

112 and QR = 19 units, find the length of arc QS.
Round to the nearest hundredth.

Answer 1

27.92 ??

Explanation:

Radius (qr) = r = 16 units

<QŘS = θ = 82°

Length of an arc = (Θ / 360) * 2πr

L = (θ / 360) *2πr

L = (82 / 360) * 2π * 16

L = 0.2777 * 100.53

L = 27.917 units

L = 27.92 unit
