If the radius of a circle is 6 inches, how long is the arc subtended by an angle measuring 70 degrees?

To find the length of the arc, we can use the formula:

Arc Length = (θ / 360) × 2πr

where:

  • θ is the angle in degrees (70 degrees in this case)
  • r is the radius of the circle (6 inches)
  • π is a constant (approximately 3.14159)

Now, substituting the values into the formula:

Arc Length = (70 / 360) × 2π × 6

First, simplify (70 / 360):

(70 / 360) = 0.1944 (approximately)

Now, plug that back into the equation:

Arc Length = 0.1944 × 2 × 3.14159 × 6

Calculating that gives:

Arc Length ≈ 0.1944 × 37.6991 ≈ 7.33 inches

Therefore, the length of the arc subtended by an angle of 70 degrees in a circle with a radius of 6 inches is approximately 7.33 inches.
