Answer:
Explanation:
The formula for determining the circumference of a circle is expressed as
Circumference = 2 × π × r
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Looking at the diagram,
The radius of the green circle is 22m. Therefore
Circumference of green circle would be
2 × 3.14 × 22 = 138.16 m
The diameter of the blue circle is the radius of the green circle
Radius = diameter/2
The radius of the green circle would be
22/2 = 11m
Therefore
Circumference of blue circle would be
2 × 3.14 × 11 = 69.08 m
