The diameter of a semicircle is 8 meters. What is the semicircle's radius?d=8 m

1. Break Down the Problem

To find the radius of a semicircle, we first need to understand the relationship between the diameter and the radius. The radius is half the length of the diameter.

2. Relevant Concepts

The formula to find the radius $r$ from the diameter $d$ is given by: $r = \frac{d}{2}$

3. Analysis and Detail

Given that the diameter $d = 8$ meters, we will substitute this value into the formula: $r = \frac{8 \, \text{m}}{2}$

4. Verify and Summarize

Calculating the value: $r = 4 \, \text{m}$ This calculation confirms that the radius is derived correctly from the diameter.

Final Answer

The radius of the semicircle is $4$ meters.
