Please help with this test, I was out of school for awhile due to my dad passing away from heart and kidney failure. I'm trying to catch up on missing work and get good grades to make my mom happy and every time I ask my teachers for help with this test they really don't help at all. The test is lesson 11 unit 3 rational numbers unit test. It's a connections academy test
Her dad just died. Show some sympathy at least. I mean- how would you feel if your dad just passed away and all you want to do is help your mom out by getting good grades?
Also, what grade is it for? I think that I can help you. @Anonymous

Triangular prism with the following measurements: 20 cm, 32 cm, 16 cm , and 12 cm.
Here are the steps:
1) 12 x 16 = 192
2) 192 / 3 = 64
3) 192 / 3 = 64
4) 192 / 3 = 64
5) 12 x 32 = 384
6) 32 x 20 = 640
7) Add Steps 2 - 6 --> 64 + 64 + 64 +384 + 640 = 1,216 cm^2 (ANSWER)
9. Use the net to find the approximate surface area of the cylinder to the nearest square meter.
There is a cylinder with a radius of 7m and a height of 11 m.
Use the value 3.14 for pi
Surface Area = 2 x pi x radius x height
= 2 x 3.14 x 7 x 11
= 483.56 m^2 ----> Rounded up ---> 484 m^2 ( ANSWER)
10. What is the volume of the prism to the nearest whole unit.
There is a rectangular box with the following measurements 11 in , 9 in, and 3 in
Step 1) Add all the measurments together
11 in + 9 in + 3 in = 23 in^3 (ANSWER)
11.) What is the volume of the triangular prism to the nearest whole unit ?
There is triangular prism, think triangular box. It has the following dimensions
2 ft , 12 ft , and 18 ft
Step 1) Multiply 2 x 12 x 18 = 432
Step 2) Double 432 --- > 432 + 432 = 864 ft^3 (ANSWER)
12.) What is the volume of the cone to the nearest whole unit?
There is a cone with with a circular radius of 6 inches and a cone height of 11 inches.
Use 3.14 for pi
Step 01) 3 x pi x radius x 2 x height
Step 02) 3 x 3.14 x 6 x 2 x 11
Step 03) 1,243.44 ----> 1, 244 in^3 ( ANSWER)
13.) What is the volume of the pyramid to the nearest whole unit?
There is a pyramid with the measurements 7yds, 9yds, and 7yds (height)
Step 01) Multiply 7 x 9 = 63
Step 02) Divide 63 / 2 = 31.5
Step 03) Multiply 31.5 by the height --> 31.5 x 7 = 220.5 Round up to 221 yd^3 (ANSWER)
14.) What is the slant height for the given pyramid to the nearest whole unit?
Pyramid base = 6 cm
Height = 4 cm
6^2 + 4^2 = C^2
6 x 6 + 4 x 4 = C^2
36 + 16 = C^2
52 = C^2
SquareRoot 52 = SquareRoot C^2
7.2 = C
Round 7.2 to the nearest whole ---> 7 cm (ANSWER)
15) What is the length of the diagonal for the given rectangular prism to the nearest whole unit?
Length = 12 cm
Width = 4 cm
Height = 9 cm
Step 01) 12 ^ 2 + 4 ^ 2 = C^2
144 + 16 = C^2
160 = C^2
SquareRoot 160 = SquareRoot C^2
12. 6 = C (Diagonal)
12.6 Rounded to the nearest whole ----> 13 cm (ANSWER)
16) The cones below are similar, although not drawn to scale.
Small Cone: r = 5ft and 15ft Big Cone = x and 18ft
Step 1) 15 / 5(r) = 3
Step 2) 18 / x (r) = 3. What number when you divide 18 by it is 3? .......It is 6 duuuhhhhh
B.) 6 (ANSWER)
17. ) A cone has a radius of 40 cm and a volume of 1,875 cm^3. What is the volume of a similar cone with a radius of 16 cm?
Step 1) 40/16 = 2.5
Step 2) Divide 1, 875 by 2.5 = 750 cm^3 (ANSWER)
18) What is the area of a sphere with a radius of 5 meters rounded to the nearest square meter?
Step 01) A = 4 x pi x r^3 ---> A = 4 x 3.14 x 5^3 ----> A = 4 x 3.14 x 5 x 5 x 5 ---> A = 1,570
Step 02) Divide the answer above , 1, 570 by 3 ---> 1,570 / 3 = 523.33 <---Round down is 523m^2
D) 523 m ^2 (ANSWER)
19.) What is the volume of a sphere with a radius of 4 meters rounded to the nearest square meter?
Step 01) Use formula = 4 x pi x r^2 --> 4 x 3.14 x 4^2 --> 4 x 3.14 x 4 x 4 ---> 200.96 m^3
Round 200.96 to the nearest whole is 201 m^3.
B) 201 m^3 (ANSWER)
20.) Find the lateral area of the square pyramid.
There is a square pyramid with the measurements 8 m , 8m and a height of 22 m
Step 01) Area ofa the Square Base 8 x 8 = 64
Step 02) Area of each Triangle 8 x 22 = 176
Step 03) There are four triangles multiply 176 x 4 = 704
Step 05) Divide 704/ 2 = 352
Step 06) Add 64 + 352 = 416 m^2 (ANSWER)
21) Find the surfacea area of the cone. Use 3.14 for pi.
There is cone with the diameter of 8 in and 7 in for slant height.
Step 01) pi x 8^2 --> 3.14 x 8 x 8 = 200.96
Step 02) 200.96 x 7 = 1 , 406.72
Step 03) 1, 402.77 divide by 3 = 468. 9 in^2 (ANSWER)
22) Find the volume of the cylinder. Use 3.14 for pi
There is a cylinder with a radius of 34 m and a height of 27
Step 01) pi x r^2
Step 02) 3.14 x 34^2 = 3.14 x 34 x 34 = 3, 629. 84
Step 03) 3,629 x 27 = 98, 005. 68 m^3 (ANSWER)
I am not taking any side cuz i don't want to be in this i just want help
I mean if her dad died he died that is sad
if not then don't lie
thats that i don't care enough to argue about it
Please do not cheat, even if your dad died, or someone died in your family, then that is still not an excuse to cheat. @Anonymous your mother would be even more proud to know that you did your best. Grades can always be fixed, your families trust and your life cant.
@Anonymous, even if your Dad isn't dead, why did someone lie for you, and why don't you stand up for yourself?
Teachers know what they are doing. Cheating isn't right. And you should know that. Didn't your parents even teach you that? Cheating, if used multiple times, will lead to banning from Connexus.
Cheating becomes a habit you forever remember. Don't do it, and you wont be in trouble about it.
