Find the circumference of both circles to the nearest hundredth.

Step-by-step explanation:

Radius of green circle (r) = 22 cm

Circumference of green circle

Diameter of blue circle = 22 m

Radius of blue circle (r) = 11 cm

Circumference of blue circle

Step-by-step 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
