2.  0-10 pts.) Describe how to find the areas of a square, rectangle, triangle, parallelogram, trapezoid, kite and rhombus. Give at least 3 examples of each.  Squares, rectangle, parallelograms are very simple to find the area you only need to multiply base times the height !

3. Ex.1 6 8 Area= 48 Ex.2 32 4 Area=128 Ex.3 87 35 Area=3045

4. Ex.1 5 8 (8x5)/2=20 Ex.2 3 10 (3x10)/2=15 Ex.3 20 6060 (20x60)/2=600

5.  To find the area of a trapezoid take the sum of its bases then multiply the sum times the height, and then divide the result by half, (b1+b2)(height)/2 Ex.1 3 5 7 (5+7)(3)/2=52.5

6. 5 10 11 Ex.2 (5+10)(11)/2=82.5 25 27 18(25+27)(18)/2=468

7.  To find the area of a kite you multiply the diagonals and then divide by half 10 7 Ex.1 7x10/2=37.5 Ex.2 3 5 3x5/2=10

8. 136 Ex.3 6x13/2= 39

9. Ex.1 8 10 Area =80 Ex.2 23 30 23x30=690 Ex.3 19 27 19x27=513

10.  IN a composite figure you have to find different types of shapes and then add them up, for example in an arrow you can divide it to a triangle and a square and you can easily find the area of both of those so you just add them to get your total area

11. Ex.15 3 1115 Triangle: 4x15/2=30 Square: 3x10=10 Total area: 40 Ex.2 5 3 10 2 8trapezoid: (10+8)(5)/2=45 5 Square: 10 Total area: 55

12. Ex.3 15 30110 Triangles: 25x40/2=500 each 55 55 Square: 30x15=450 Total area: 1450

13.  Pi times the radius squared 3 Ex.1Ex.2 5 28.27 78.53 Ex.3 13 530.92

14.  They are three dimensional figures for example pyramids, prisms and other three dimensional figures. To find the surface area you need to add up all of the surface areas Ex.1 2 2 2 2 24 4 2

15.  The surface area is just all of the faces of the prism added up. So a prism is a solid figure with two opposite faces similar, equal, and parallel their sides must also be parallelograms. The net is when you flatten out all of the faces of the figure. Ex.1

16. Ex.2 Ex.3

17. TO find the surface area you add the surface area of all of the parts of the cylinder. The bases of the cylinder are circles so you use pi r squared. Then to find the surface area of the side you multily the circumference times the height. Ex.1Ex.2 Ex.3 6 7 36.82 3 14 42.53 9 4 58.68

18.  First you need to find the lateral surface area, which is the side triangles. Then just add the base. 5 3 15+2.5=17.5 1 Ex.1 6 4 3 Ex.2 12+9=21 3 2 Ex.3 24

19.  To find the area is you multiply pi times the radius times a side. Then add pi times the radius squared which is the base circle. Ex.1 3 5 18 Ex.2 8 6 46 Ex.3 4 6 23

20.  This is simple just get a side and cube it (to the power of 3) 3 Ex.1 Ex.2 48 64 Ex.3 512 27

21.  If two geometrical figures have the same height and width they have the same volume = = = Ex.1Ex.2 Ex.3

22.  prism = length × width × height Ex.1 3 3 3 27 Ex.2 2 2 2 8 4 4 4 Ex.3 64

23. Pi times the radius squared Ex.1 7 4 Pi times 4 squared times 7+351 Ex.2 4 2 100 Ex.3 2 17 213

24.  You multiply the area of the base times height

25.  Pi times radius squared times height Ex.1 3 5 47Ex.2 4 8 134 Ex.3 13 4 708

26.  Pi times the radius squared

27.  Cube the radius then multiply by 4 and then divide by 3
