1) C 2) D 3) C 4) A 5) B An octahedron has 12 edges and 6 vertices. 6) C Plus, 180 degree rotation 7) B Area of a square = side 2 To figure out the side, use Pythagorean theorem

Then, plug it into the area formula 8) C Area = Area = 9) C Circumference = 10)B Perimeter = sum of sides 11)C Surface Area = height x circumference + 2(Area of circle) Surface Area = height x + 2() 12)D Volume = length x width x height 13)C The original shape moved down and then reflected itself. This is called a Glide- reflection. 14)D The original shape reflected over that corner point. 15)B

16)A If the cylinders are similar, the height and radius should have the same ratio. = 8:1 17)D You need to know what type of polygon you have in order to figure out this

Unformatted text preview: problem. Also, none of these can be the answer since they all have the wrong units. Area should be square meters. 18)C 19) B Golden triangles are isosceles triangles 20)D The temperature dropped 8 degrees Celsius. 78.8 68 = 10.8 21)A 389 x 8 = 3112mg or 3.1g 22)B V E + F = 2 13 E + 21 =2 34 E = 2 E = 32 23)This general idea 24)Volume of Cone= Volume of Cylinder = = divide both sides by pi and r 2 = So, the answer is yes. If you were given the height of the cylinder, plug that value in for h 2 and solve for h 1 . 25) Answer will vary. Some include 1) C 2) D 3) C 4) A 5) B 6) C 7) B 8) C 9) C 10) B 11) C 12) D 13) C 14) D 15) B 16) A 17) D 18) C 19) B 20) D 21) A 22) B...
