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)

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)
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.
