Q. The diameter of a semicircle is

6\,\text{millimeters}

. What is the semicircle's radius?

\newline

\_\_\_\_\_\_

millimeters

Understand relationship between diameter and radius: Step $1$ : Understand the relationship between diameter and radius. $\newline$ The radius is half of the diameter. $\newline$ Calculation: Radius = Diameter / $2$ = $6 \, \text{mm} / 2$ .
Calculate the radius: Step $2$ : Calculate the radius. $\newline$ Radius = $3\,\text{mm}$ .
