What is the arc length if θ = 6π/5 and the radius is 2 cm?

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

s = rθ

where:

  • s is the arc length
  • r is the radius of the circle
  • θ is the angle in radians

In this case, the radius (r) is 2 cm and the angle (θ) is 6π/5 radians. Plugging these values into the formula gives:

s = 2 * (6π/5)

Calculating this:

s = (12π/5) cm

This is the arc length. To get a numerical value, you can approximate π as 3.14:

s ≈ (12 * 3.14/5) ≈ 7.54 cm

So, the arc length for the given angle and radius is approximately 7.54 cm.
