Enter the radius or the diameter Radius (r) Diameter (d) Radius, Diameter, Area, and Circumference A circle is defined by a single measurement: its radius, the distance from the center to any point on the edge. The diameter is simply twice the radius, the distance straight across the circle through its center, so d =…

Find the distance between two points Point 1 (x₁, y₁) Point 2 (x₂, y₂) The Distance Formula and the Pythagorean Theorem The distance formula finds the straight-line distance between two points on a coordinate plane, (x₁, y₁) and (x₂, y₂), using d = √((x₂ − x₁)² + (y₂ − y₁)²). It is not a separate…
