A circle has a radius of 10 inches. Find the approximate length of the arc intersected by a central angle of [tex]$\frac{2 \pi}{3}$[/tex].

A. 6.67 inches
B. 10.47 inches
C. 20.94 inches
D. 62.8 inches

Answer :

To find the length of the arc of a circle, you can use the formula:

[tex]\[ \text{Arc Length} = \text{Radius} \times \text{Central Angle in Radians} \][/tex]

Here, we have:

- The radius of the circle is 10 inches.
- The central angle is [tex]\(\frac{2\pi}{3}\)[/tex] radians.

Now, let's calculate the arc length:

1. Substitute the Values Into the Formula:

[tex]\[ \text{Arc Length} = 10 \, \text{inches} \times \frac{2\pi}{3} \][/tex]

2. Calculate the Result:

[tex]\[ \text{Arc Length} = 10 \times \frac{2\pi}{3} \][/tex]

[tex]\[ \text{Arc Length} \approx 20.94 \, \text{inches} \][/tex]

So, the approximate length of the arc is 20.94 inches.

Therefore, from the given options, the correct answer is 20.94 inches.
