Final answer:
To find the arc length, multiply the radius by the central angle.
Step-by-step explanation:
To find the arc length, we can use the formula:
Arc length = radius * central angle
Given that the radius is 18m and the central angle is T/6, we substitute these values into the formula:
Arc length = 18m * (T/6)
We can simplify this expression by canceling out the 6 in the denominator:
Arc length = 3m * T
The arc length is 3T meters.
