Across
- 2. In mathematics, area is the measure of the amount of two-dimensional space occupied by a flat, 2D shape or surface
- 6. the enclosing boundary of a curved geometric figure, especially a circle.
- 10. A chord in mathematics is a straight line segment connecting any two points on a curve.
- 12. an angle whose vertex is exactly at the center of a circle
- 14. Pi (π) is a mathematical constant that represents the ratio of a circle’s circumference (distance around) to its diameter (distance across)
- 15. Diameter is the straight-line distance across the center of a circle or sphere, connecting two opposite points on its edge
Down
- 1. a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.
- 3. a part of the circumference of a circle or other curve
- 4. a scent is a line that goes from one one point to another
- 5. (of a surface or object) marked with characters.
- 7. A circle is a perfectly round geometric shape in a 2D plane. It is defined as a set of all points that are an equal distance (the radius) from a single fixed center point.
- 8. forming, situated on, or relating to the outside of something.
- 9. at right angles to a horizontal plane; in a direction, or having an alignment, such that the top is directly above the bottom.
- 11. the middle point of a circle or sphere, equidistant from every point on the circumference or surface.
- 13. A radius is a straight line from the center of a circle or sphere to its outer edge. It also refers to the length of that line
