Final answer:

The arc length of the circle with a radius of 5.5 cm and a central angle of 5/2 radians is approximately 785 cm.

Step-by-step explanation:

The arc length of a circle can be found using the formula:

Arc Length (s) = Radius (r) * Central Angle (θ)

In this case, the radius is given as 5.5 cm and the central angle is given as 5/2 radians. Convert 5/2 radians to degrees by multiplying by 180/π:

θ = (5/2) * (180/π) = 450/π degrees

Now substitute the values into the formula:

s = 5.5 cm * (450/π) degrees

Calculate the approximate value of π as 3.14 and simplify the expression:

s ≈ 5.5 cm * (450/3.14) ≈ 785 cm

Therefore, the arc length of the circle is approximately 785 cm.
