1. #1, #2 are correct
#3 - #9 need a look at the diagrams, which of course we can't post here

#10 - #12 look good
#13 ----- need diagram, can't tell which numbers go where
#14 --- need diagram
#15 , I guessed what you meant, looks ok
#16
18/15 = x/5
15x = 90
x = 6

#17
volumes of similar objects are proportional to the cube of their corresponding sides
x/1920 = 18^3/24^3 = (3/4)^3 = 27/64
64x = 27(1920)
x = 27(1920)/64 = 810

#18
SA of sphere = 4πr^2 <----- you must know that!
= 4π(25) = 100π = 314 to the nearest m^2

8. What is the surface area of the given figure?
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)

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

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.

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

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

10. for the most part, chocolate unicorn is actually right
maybe not completely but hey it'll b a passing grade
some question's lengths and heights get changed up as well so i'd recommend using surface area, volume, etc, calculators on as many as you can
also, for number 2 its actually a cone
