To find the diameter of the circle, we first need to find the radius using the formula for the circumference of a circle:
Circumference = 2 * π * radius
69.08 = 2 * 3.14 * radius
69.08 = 6.28 * radius
radius = 69.08 / 6.28
radius ≈ 11
Now that we have the radius, we can find the diameter by multiplying the radius by 2:
Diameter = 2 * radius
Diameter = 2 * 11
Diameter = 22
Therefore, the diameter of the circle is 22 cm.
