Using the arc length formula, the length of the outer curve is approximately 85 feet.
<h3>How to Find the Length of an Arc?</h3>
Arc length = ∅/360 × 2πr.
Apply the arc length formula to find the length of the outer curve, given the following:
- ∅ = 70°
- π = 3.14
- r = 50 + 20 = 70 feet
Plug in the values
Arc length = 70/360 × 2(3.14)(70)
Arc length = 70/360 × 2(3.14)(70) ≈ 85 feet.
The length of the outer curve is approximately 85 feet.
