Q. The diameter of a semicircle is

6\,\text{meters}

. What is the semicircle's radius?

\newline

\_\_\_\_\_

meters

Understand the problem: Step $1$ : Understand the problem. We need to find the radius of a semicircle whose diameter is $6$ meters.
Apply formula: Step $2$ : The formula to find the radius $r$ from the diameter $d$ is $r = \frac{d}{2}$ . Here, $d = 6$ meters.
Calculate radius: Step $3$ : Calculate the radius. $r = \frac{6}{2} = 3$ meters.
