Question

Find the length of JL.8M71%83°KNote: Use either the pi button on your calculator or 3.14 for pi. Round to the nearest tenth.

Answer 1

Okay, here we have this:

We need to find the arc length, so replacing in the arc lenght formula we obtain:

Arc length = theta/360 * 2πr

Theta = JL angle

r=8

Therefore:

Arc length = 71/360 *2π(8)=142π/45=9.9 units.
