Question

Please help! Find the length of each arc. Do not round. Put answers in terms of pi.

Answer 1

• 14π cm

---------------------

Use the formula:

• s = (θ/360) × 2πr,

where θ is the central angle in degrees, r is the radius

We have:

• θ = 315 and r = 8.

Substituting the given values, we get:

• s = (315/360) × 2π(8)
• s = (7/8) × 2π(8)
• s = 14π

Therefore, the length of the arc is 14π cm.
