Question

find the circumference of each circle. 1)

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference of a circle is \(C = 2\pi r\), where \(r\) is the radius.

Step2: Substitute the given radius

Given \(r = 4.5\) m. Substitute into the formula: \(C=2\times\pi\times4.5\).

Step3: Calculate the value

\(C = 9\pi\approx9\times3.14 = 28.26\) m.

Answer:

The circumference of the circle is approximately \(28.26\) m.
