  1. 2. A mathematical constant approximately equal to 3.14, used to calculate the circumference and area of circles.
  2. 3. Area The total area of all the surfaces of a three-dimensional object.
  3. 6. The distance from the center of a circle to any point on its edge.
  4. 7. The bottom surface of a three-dimensional object, often used to support the object.
  5. 8. A flat surface on a three-dimensional object; a cube has six faces.
  6. 11. The distance around a circle, calculated using the formula C = 2\pi r, where r is the radius.
  7. 14. A four-sided polygons that include shapes like squares, rectangles, and trapezoids.
  8. 15. The total distance around a two-dimensional shape, found by adding the lengths of all its sides.
Down
  1. 1. Figure A figure that is a shape that is made up of two or more simple geometric shapes combined together.
  2. 4. The distance across a circle through its center, equal to twice the radius; calculated as D = 2r.
  3. 5. A round shape where every point on the edge is the same distance from the center.
  4. 9. The amount of space inside a two-dimensional shape, measured in square units.
  5. 10. The amount of space inside a three-dimensional object, measured in cubic units.
  6. 12. Prisms A three-dimensional objects with two parallel bases that are congruent and rectangular sides; the sides meet at right angles.
  7. 13. A three-dimensional objects with six equal square faces, twelve edges, and eight vertices.
