Let's assume that the green circle has a circumference of 20 meters. The formula for the circumference of a circle is:
C = 2πr
where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
To find the radius of the green circle, we can rearrange the formula as:
r = C/2π
Plugging in the given circumference of 20 meters, we get:
r = 20/(2π) ≈ 3.18 meters
Therefore, the green circle has a radius of about 3.18 meters.
To find the circumference of the blue circle, we can use the same formula:
C = 2πr
but with a different value of the radius. Let's assume that the blue circle has a radius of 5 meters. Then, its circumference would be:
C = 2π(5) = 10π ≈ 31.42 meters
Rounding this value to the nearest hundredth, we get a circumference of about 31.42 meters. Therefore, the circumference of the blue circle is about 31.42 meters.
