Question

1. find the circumference. 6 cm

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 value of radius

Given \(r = 6\) cm. Substitute into the formula: \(C=2\times\pi\times6\).

Step3: Calculate the result

\(C = 12\pi\) cm. If we take \(\pi\approx3.14\), then \(C=12\times3.14 = 37.68\) cm.

Answer:

If using \(\pi\approx3.14\), the circumference is \(37.68\) cm. If keeping it in terms of \(\pi\), the circumference is \(12\pi\) cm.
