  2. perimeter • the border or outer boundary of a two-dimensional figure. • Square P=4s • Rectangle p=2l+2w or p=2(l+w)

  3. Word problem What is the perimeter of a square if the side length is 2. Solution 8 What is the perimeter of a rectangle if if the length is 4 an the width is 2. Solution is 12

  4. circumference • The area of a circle, the outer boundary. • Example, Circle C=2 r or *d

  5. Word problem • What is the circumference of a circle if the diameter is 4. • Solution 12.66

  6. Area • The area within the space , the space or site on which a building stands; the yard attached to or surrounding a house. • Square A=s2 • Rectangle A=lw • Triangle A=bh /2 • Trapezoid A=1/2(b1+b2)h • Circle A=pi*r2

  7. Word problem • What is the area of a square if the side is 4. • Solution 16 • What is the area of a rectangle if the length is 5 an the width is 2. • Solution is 10 • What is the area of a triangle if the base is 5 an the height is 8 • Solution is 20

  8. Word problem • What is the area of a trapezoid if the half # is 5 an b1 is 2 an b2 is 2 an height is 10 • Solution 200

  9. Big P • The perimeter of the base of a three dimensional figure.

  10. Big B • The area of the base of a three dimensional figure.

  11. Surface area • Cube (total) s=6s2 • Prism (lateral) s=Ph • Pyramid (lateral) s=1/2 pl • Pyramid (total) s=1/2 pl +b • Cylinder (lateral) s=2*pi*r*h • Cylinder (total) s=pi*r*h+2*pi*r2 • The extent of a 2-dimensional surface enclosed within a boundary.

  12. Word problem • What is the surface area of a cube if the side is 4 • Solution is 96 • What is the surface area of a prisms side if big p is 8 an the height is 10 • Solution is 80 • What is the surface area of a prymaid

  13. Volume • the amount of space, measured in cubic units, that an object or substance occupies. • Prism V=Bh • Cylinder V=Bh • Pyramid v=1/3Bh • Sphere V=4/3 pi*r3 • Cone v=1/3 Bh

  14. Word problem • What is the volume of a prism if big B is 4 an height is 8. • Solution 32 • What is the volume of a cylinder if big B is 6 an the height is 9. • Solution is 54 • What is the volume of a pyramid if the 1/3 is 2 an big b is 8 an height is 4 • Solution is 64

  15. Pi • =3.14 or 22/7

  16. Pythagorean theorem • A2+b2=c2 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.

  17. Word problem • A2+b2=c2

  18. Simple interest formula • I = prt • I = prt • Where,I = interestP = principalr = interest rate (per year)t = time (in years or fraction of a year)

  19. Word problem • I = prt

  20. PEMDAS • P=Punctuations • E=Exponents • M=Multiply • D=Divide • A=Add • S=Subtract

  21. Word problem • (2*7)5 • Solution 70

  22. 3d shapes • Shapes that have 3 dimensions

  23. 2d shapes • Shapes that have 2 dimensions
