2. VOLUME  The amount of an object that takes up space.  Prism V=Bh  Cylinder V=Bh  Pyramid V= 1 3 Bh  Cone V= 1 3 Bh  Sphere V= 4 3 3.14r 2

3. Question?  What is the volume of a rectangle prism if the height = 5cm and the with = 10cm? Answer=250cm

4. circumference The area within a bounding line: the vast circumference of his mind. Circle C=2*pi*r

5. Question? What is the circumference of the circle if the diameter 5cm? Answer=15.7

6. Perimeter The perimeter is the borderor outer boundary of a two-dimensional figure. Square R=4s Rectangle P=2l+2w or P=(l+w) Square P=4s

7. Big question?  What is the perimeter of a square if all of the sides equal 7cm? Answer=28cm

8. Pi  A transcendental number, fundamental to mathematics, that is the ratio of the circumference of a circle to its diameter. Approximate value: 3.141 5927…; symbol: ∏  ∏ ∏=3.14

9. Word problem?  What is the area of the circle if the radius = 7 Answer=

10. Pythagorean theorem  The theorem that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.  Pythagorean theorem a 2 +b 2 =c 2

11. Simple interest formula  Simple interest formula I=prt

12. Area  any particular extent of space or surface; part: the dark areas in the painting; the dusty area of the room.  Square A=s  Rectangle A=lxw or A=bh  Triangle A= 1 2  Trapezoid A= 1 2  Circle A=3.14xrx 2

13. Question?  What is the area of the square? 10cm 6cm Answer=16

14. Big P  P represents the perimeter of the base of all three-dimensional figure.

15. Big B  B represents the area of the base of a three- dimensional figure.

16. Question?  What is the volume of the cylinder if the area = 112? Answer=175.84

17. Area of the base  Base area is length times width  B represents the area of the base of a three- dimensional figure.

18. 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. arc length  Cube (total) S=6s 2  Prism(lateral) S=Ph  Prism(total) S=Ph+2B  Pyramid(lateral) S= 1 2 Pl  Pyramid(total) S= 1 2 Pl=B  Cylinder(lateral) S=23.14rh  Cylinder(total) S=23.14rh=23.14r 2

19. Function notation  A notation that describes a function

20. Ratios  A "ratio" is just a comparison between two different things.... Given a pair of numbers, you should be able to write down the ratios.

21. P.E.M.D.A.S.  Parenthesis()  Exponents Multiply (x) Divide Add (+) Subtract(-) (÷)
