If the diameter 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 subtended by an angle in a circle, we can use the formula:

L = (θ / 360) × C

where L is the arc length, θ is the angle in degrees, and C is the circumference of the circle.

First, we need to calculate the circumference (C) of the circle. The formula for the circumference is:

C = π × d

where d is the diameter. Here, the diameter is 6 inches, so:

C = π × 6 ≈ 18.85 inches.

Next, we can substitute the values into the arc length formula. The angle θ is 70 degrees:

L = (70 / 360) × 18.85 ≈ 36.45 inches.

Therefore, the length of the arc subtended by a 70-degree angle in a circle with a diameter of 6 inches is approximately 3.65 inches.
