question
the diameter of a circle is 18 cm. find its circumference in terms of π.
answer attempt 1 out of 2

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference \(C\) of a circle is \(C = \pi d\) (where \(d\) is the diameter).

Step2: Substitute the value of diameter

Given \(d = 18\) cm. Substitute \(d = 18\) into \(C=\pi d\). So \(C=\pi\times18 = 18\pi\) cm.

Answer:

\(18\pi\) cm
