  2. Word Problem: Mrs. Dunwoody needs carpet to measure the perimeter of her whole house. Which can she determine of how much carpet she needs? Answer:A=lxwxh Perimeter- the border or outer boundary of a two-dimensional figure. And the length of such a boundary. a line bounding or marking off an area and the outermost limits.

  3. Circumference-C=2(3.14)r Word Problem: A student is drawing a circle to find the Circumference of the circle. how can they find the circumference? The circumference of a circle is the length around it. The circumference of a circle can be calculated from its diameter using the formula: Or, substituting the radius for the diameter: where r is the radius and d is the diameter of the circle, and π (the Greek letter pi) is defined as the ratio of the circumference of the circle to its diameter Answer:C=3.14 marthalakecov.org

  4. Surface Area Surface area is the measure of how much exposed area a solid object has, expressed in square units. Mathematical description of the surface area is considerably more involved than the definition of arc length of a curve. For polyhedra (objects with flat polygonal faces) the surface area is the sum of the areas of its faces. Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces. This definition of the surface area is based on methods of infinitesimal calculus and involves partial derivatives and double integration.

  5. A cone is a three-dimensional shape that has 2 faces, 1 base, 1 vertex and 1 edge. The formula for the volume of a cone can be determined from the volume formula for a cylinder--in fact, you follow the exact same formula, and then you divide your answer by 3. You can calculate the volume of a cone using these simple steps Word Problem: Volume A student was observing a cone and wants to figure out how to find the volume of the cone Answer:V=1/3Bh

  6. A circle has a radius of 1.50 Pi 3.14 is a mathematical constant whose value is the ratio of any circle's circumference to its diameter in Euclidean space; this is the same value as the ratio of a circle's area to the square of its radius. vijayforvictory.com

  7. Pythagorean theorem Pythagorean theorem or Pythagoras' theorem is a relation in Euclidean geometry among the three sides of a right triangle (right-angled triangle). In terms of areas, it states: In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).

  9. Word Problem: What is the area of this square? Answer:4+4+4+4=16 Square P=4s In geometry, a square is a regularquadrilateral. This means that it has four equal sides and four equal angles (90 degree angles, or right angles). wall.org

  10. Word Problem: Mrs.zamora has a rectangle table and wants to find the perimeter of the table. What is the perimeter of the rectangle? Answer:10+10+5+5=30cm Rectangle a rectangle is any quadrilateral with four right angles. The term "oblong" is occasionally used to refer to a non-square rectangle P=2l+2w tutorvista.com

  11. Word Problem: Mrs.rhine is wanting to find the circumference of the circle .What is the circumference of the circle? Answer:C=3.14 Circle A circle is the locus of all points equidistant from a central point C=2X3.14R tutorvista.com

  12. Word Problem: A student is trying to find the height of a triangle.What is the height? Answer:H=30cm Triangle A triangle is one of the basic shapes of geometry: a polygon with three corners or vertices and three sides or edges which are line segments A=1/2bh library.thinkquest.org

  13. Word Problem: Another student wants to find the pereimeter of a trapezoid.what is the perimeter? Answer:3+5+10+8=26cm Trapezoid a four-sided figure with one pair of parallel sides is referred to as a trapezoid in American English and as a trapezium in English outside North America. A=1/2(b1+b2)h k6-geometric-shapes.com

  14. Word Problem: A cube has a height of 5in. And a base of 25in.what is the area of the cube? Answer:140cm. Cube The film was a successful product of the Canadian Film Centre's First Feature Project.[1] Despite its low budget, the film achieved moderate commercial success and has acquired cult status S=6s2 talkstandards.com

  15. Prism a prism is a transparent optical element with flat, polished surfaces that refractlight. The exact angles between the surfaces depend on the application. The traditional geometrical shape is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use "prism" usually refers to this type. S=PH+2B mathsteacher.com.au

  16. A pyramid (from Greek "πυραμίς" - pyramis[1]) is a structure where the outer surfaces are triangular and converge at a point. The base of a pyramid can be trilateral, quadrilateral, or any polygon shape, meaning that a pyramid has at least three triangular surfaces (at least four faces including the base).

  17. Cylinder S=2(3.14)rh+2(3.14)r2 A cylinder is one of the most basic curvilinear geometric shapes, the surface formed by the points at a fixed distance from a given line segment, the axis of the cylinder. The solid enclosed by this surface and by two planes perpendicular to the axis is also called a cylinder. The surface area and the volume of a cylinder have been known since deep antiquity. teacherfiles.com

  18. Cone A cone is a three-dimensionalgeometric shape that tapers smoothly from a flat, usually circular base to a point called the apex or vertex. More precisely, it is the solid figure bounded by a plane base and the surface (called the lateral surface) formed by the locus of all straight line segments joining the apex to the perimeter of the base. daviddarling.info

  19. Sphere A sphere (from Greekσφαῖρα—sphaira, "globe, ball") is a perfectly round geometrical object in three-dimensional space, such as the shape of a round ball. Like a circle in two dimensions, a perfect sphere is completely symmetrical around its center, with all points on the surface lying the same distance r from the center point. accad.osu.edu
