The diameter of a semicircle is the same as the diameter of a full circle. The formula for the diameter of a semicircle is simply the length of the straight line that passes through the center of the semicircle and touches two points on its edge. This line is the same as the diameter of the full circle from which the semicircle is derived.
To calculate the diameter of a semicircle, you can use the formula:
**Diameter (D) = 2 × Radius (r)**
Where:
– **D** is the diameter of the semicircle.
– **r** is the radius of the semicircle.
For example, if the radius of a semicircle is 5 units, the diameter would be:
**D = 2 × 5 = 10 units**
This formula is straightforward and helps in determining the diameter when the radius is known.
