What is the arc length when the angle is 8π/5 radians and the radius is 6 cm?

To calculate the arc length (s) of a circle, we can use the formula:

  • s = r × θ

Where:

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

In this case, you have:

  • r = 6 cm
  • θ = 8π/5 radians

Now, we can plug the values into the formula:

s = 6 cm × (8π/5)

Calculating this gives:

s = (48π/5) cm

If we want a numerical value, we can approximate π as 3.14:

s = (48 × 3.14) / 5

Which equals approximately:

s ≈ 30.16 cm

So, the arc length when the angle is 8π/5 radians and the radius is 6 cm is approximately 30.16 cm.
