Asst 3

I tried to send this work the other way, but every time I do, this is what comes up -- run-time error '9' Subscript out of range I'm sorry about sending my work late but my computer keeps messing up - Hopefully it is fixed now -- Also, what tests do I need to take?

Tell me what specific program you are running and exactly what you are putting into the program, step by step, keystroke by keystroke.

3. The formula for the circumference C of a circle of radius r is: Circumference equals 2 Pi r = pi d

6. False - The volume of a sphere of radius r is 4/3 Pi r^3

9. a = 10 b = 24 c^2 = a^2 + b^2 C^2 = 10^2 + 24^2 = 100 + 576 = 676 C = Sq.root of 676 = 26

12. a = 14 b = 48 C^2 = 14^2 + 48^2 = 196 + 2304 = 2500 C = Square root of 2500 = 50

15. 4, 5, 6 = 4^2 = 16 5^2 = 25 6^2 = 36 This is not a right triangle because the first 2 sides squared did no equal last side

18. 10, 24, 26 10^2 = 100 24^2 = 576 26^2=676 Yes, this is a right triangle because the first 2 sides equal to the last side

21. Area of Rectangle = LxW Length - 4 inches width - 2 inches 4 x 2 = 8^2

24. Area of triangle with height 9 centimeters and base 4 centimeters Area = 1/2 bh = 1/2(4x9) = 1/2(36) = 18

27. Find volume V and surface S of a rectangular box with lenght 8 feet, width 4 ft., and height 7 ft. Volume = lwh Surface Area = 2lw + 2lh + 2wh 2(8)(4) + 2 (8)(7) + 2(4)(7) = 2(32) + 2(56) + 2(28)= 64 + 112 + 56 = 232

30. Find volume V and surface area S of a sphere of radius 3 feet Volume = 4/3 Pi r^3 Surface area = 4 Pir^2

33. A = Pi r^2 = Pi 1^2

36. A = Pi r^2 = Pi 2^2

39. ABCD is a square with each side of lenght 6 feet. The width of the border (shaded portion) between the outer square EFGH and ABCD is 2 feet. Find the are of the border. Area = 1/2ab 1/2(8)(24) 4x2 + 6x4 = 8 x 24 = 192/2 = 96

42. A circular swimming pool 20 ft. in diameter, is enclosed by a wooden deck that is 3 ft. wide. What is the area of the deck? How much fence is required to enclose the deck? Area = LW 3x20 = 60 Area 60 ft. of fence is required

45. ????? 48.

Your work looks good--it definitely appears that you understand the material. However I can't give you specific detailed feedback except through the query program.

Let me know if you have questions.
