Question

1. a circle has radius 6 cm. find its circumference (use π = 3.14).

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference of a circle is $C = 2\pi r$.

Step2: Substitute the given values

Given $r = 6$ cm and $\pi=3.14$, we substitute into the formula: $C=2\times3.14\times6$.

Step3: Calculate the result

$C = 37.68$ cm.

Answer:

$37.68$ cm
