Question

A circle has a diameter of 12 m. What is its circumference? Use 3.14 for it, and do not round your answer. Be sure to include the correct unit in your answer. 12 m 0 m X m² Ś m³ ?

Answer 1

Explanation

We are required to determine the circumference of a circle with diameter 12m.

This is achieved thus:

We know that the cirumference of a circle is given as:

$\begin{gathered} C=2\pi r \\ where \\ \pi=3.14 \\ r=\frac{D}{2} \end{gathered}$

Therefore, we have:

$\begin{gathered} C=2\pi r \\ where \\ r=\frac{12}{2}=6m \\ C=2\times3.14\times6 \\ C=37.68m \end{gathered}$

Hence, the answer is:

$C=37.68m$
