question
the radius of a circle is 12 cm. find its circumference in terms of π.
answer attempt 1 out of 2
c = cm submit answer

Explanation:

Step1: Recall the formula for the circumference of a circle

The formula for the circumference \(C\) of a circle is \(C = 2\pi r\) or \(C=\pi d\) (where \(r\) is the radius and \(d = 2r\) is the diameter). Given \(r = 12\) cm.

Step2: Substitute the value of \(r\) into the formula

Substitute \(r = 12\) into \(C = 2\pi r\). So \(C=2\pi\times12\).

Step3: Simplify the expression

\(C = 24\pi\)

Answer:

\(24\pi\)
