Question

Find the diameter of a circle (in $cm$), if the radius is $13.2\mathrm{mm}$.

Answer 1

Given that

Radius = $13.2\mathrm{mm}$

As we know that, $Diameter=2\times Radius$

$$\begin{gathered} \mathrm{Diameter}=2\times 13.2 \\ =26.4\mathrm{mm} \end{gathered}$$

Hence, the diameter of the circle is $26.4\mathrm{mm}.$
