Which measurement is used to determine the smallest circle that contains all fired shots in a controlled drill?

• A. Diameter of the Smallest Circle Containing All Shots
• B. Sum of Distances from Each Shot to Center
• C. Average Distance Between Shots
• D. Longest Shot Distance from Center

Answer: (A)

The measurement is about capturing how spread out the shots are by using the smallest circle that can cover all of them. This is known as the minimum enclosing circle. Its size is defined by the distance across the circle, which is the diameter (twice the radius). The radius itself is the maximum distance from the circle’s center to any shot, and the center is chosen to minimize that maximum distance. So the diameter of that smallest enclosing circle is the most direct, meaningful way to quantify the overall spread of the shots. Other options don’t describe the boundary of a circle covering all shots: summing distances to a center doesn’t define containment, average distances between shots don’t indicate boundary size, and the longest distance from a center to a shot requires a center but doesn’t by itself define the enclosing circle’s size.
