What is the length of the arc subtended by a 70-degree angle in a circle with a radius of 6 inches?

To find the length of the arc subtended by an angle in a circle, you can use the formula:

Arc Length (L) = (θ / 360) * 2 * π * r

Where:

  • L = arc length
  • θ = angle in degrees (70 degrees in this case)
  • r = radius of the circle (6 inches)

Now, let’s substitute the values into the formula:

L = (70 / 360) * 2 * π * 6

Calculating step by step:

1. Calculate the fraction: 70 / 360 = 0.1944 (approximately)

2. Calculate 2 * π * 6: 2 * 3.14159 * 6 = 37.6991 inches (approximately)

3. Multiply the fraction by the circumference: 0.1944 * 37.6991 ≈ 7.328 inches

The length of the arc is therefore approximately 7.33 inches.
