Drawing a Complete Circle
Mark a midpoint M and draw circles with various radii (3 cm, 3.5 cm, 40 mm). Label each circle's radius and diameter and measure their lengths.

Labeling and Measuring
For circles with known radii (5 cm, 30 mm), calculate the diameter and verify by measuring. For circles with given diameters (8 cm, 90 mm), calculate the radius first.

Circle Geometry
Midpoint M: The center point of a circle. Radius (r): The distance from the center of the circle to any point on its circumference. Diameter (d): A line segment that passes through the center of the circle and whose endpoints lie on the circle. Circumference: The perimeter or boundary line of a circle.
