Question

the radius of a circle is 12 cm. find its circumference in terms of π.

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the value of radius

Given $r = 12$ cm. Substitute $r$ into the formula: $C=2\pi\times12$.

Step3: Calculate the result

$2\pi\times12 = 24\pi$ cm.

Answer:

$24\pi$ cm
