Question

the diameter of a circle is 16 cm. find its circumference in terms of π.

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 given diameter

Given \(d = 16\) cm. Substitute \(d\) into the formula: \(C=\pi\times16\).

Answer:

\(16\pi\)
