Step-by-step Solution
To find the arc length along a circle, we can use the formula:
\[ \text{Arc Length} = \text{Radius} \times \text{Angle in Radians} \]
Given:
- Radius = 16 units
- Angle = \( \frac{7 \pi}{6} \) radians
Substitute the values into the formula:
\[ \text{Arc Length} = 16 \times \frac{7 \pi}{6} \]
Now, we can calculate the arc length by multiplying the radius by the angle in radians.
Calculate the value by following steps:
- step0: Calculate:
\(16\times \frac{7\pi }{6}\)
- step1: Reduce the numbers:
\(8\times \frac{7\pi }{3}\)
- step2: Multiply:
\(\frac{8\times 7\pi }{3}\)
- step3: Multiply:
\(\frac{56\pi }{3}\)
The arc length along the circle is approximately 58.6 units when rounded to the nearest tenth.
Quick Answer
Arc Length ≈ 58.6
