Q. The radius of a semicircle is 5 kilometers5\,\text{kilometers}. What is the semicircle's diameter?\newline_____\_\_\_\_\_ kilometers
  1. Understand Problem: Step 11: Understand the problem and identify what is asked.\newlineWe need to find the diameter of a semicircle when the radius is given as 55 kilometers.
  2. Apply Relationship: Step 22: Apply the relationship between radius and diameter.\newlineThe formula to find the diameter from the radius is diameter=2×radius\text{diameter} = 2 \times \text{radius}.
  3. Plug in Radius: Step 33: Plug in the given radius into the formula.\newlineDiameter = 2×52 \times 5 kilometers.
  4. Perform Calculation: Step 44: Perform the calculation.\newlineDiameter = 1010 kilometers.
