14

20

Answer 8

yup

Answer 9

you are good enough to pass the course. hehehe. I am useless here.

Answer 10

idk i feel like i just want to make sure just in case @OOOPS

Answer 11

Find the diameter of a cone that has a volume of 83.74 cubic inches and a height of 5 inches. Use 3.14 for pi.


and i got 4 if you round

Answer 12

but how can you know other people is better or worse than you? how can you trust me?

Answer 13

thats true but i feel like i i get the same answer and so does the other person they it must be right cause we can't make the same mistake coincidentally you know?

Answer 14

for this one, I got 7.99 , so that if round, it should be 8
my work: V =\(\dfrac{\pi r^2 h}{3}\) so that \(r^2 = \dfrac{3V}{\pi h} =\dfrac{3*83.74}{3.1415*5}= 15.99\) --> r =\(\sqrt{15.99}= 3.99 , but that is radius, the question is about diameter --> d = 2r = 7.99 near 8

Answer 15

Oh ok btw thank you for showing your work it helps me understand

Answer 16

ok

Answer 17

A cone has a volume of 6 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?


i got 16in cubed

Answer 18

how?

Answer 19

6*3 = 18, not 16
we have the formula like this. the cone inside: \(\large V_{cone} = \dfrac{1}{3} \pi r^2 h\)
and the volume of the cylinder outside \(\large V_{cylinder}= \pi r^2 h\)
so that the \(3V_{cone}= V_{cylinder}\) and our V(cone ) is = 6 --> V(cylinder )= 18
got me?

Answer 20

yes i though i said 18 lol thank you

Answer 21

Find the area of a circle with a diameter of 22 inches. Use 3.14 for pi.


i got 379.94 in squared

Answer 22

yup

Answer 23

ok yay i'm so happy

Answer 24

There are 252 pieces of candy in a 14-ounce jar. How many pieces of candy are there per ounce in the jar?


this i got 18 cause 252/14 = 18

Answer 25

Good student. you are correct again.:)

Answer 26

ok thank you btw this is the last one

The volume of a fish tank is 20 cubic feet. If the density is 0.2fish over feet cubed, how many fish are in the tank?




p = md

0.2 = m/20

20 * 0.2 = m
m = 4 ?

Answer 27

yup

Answer 28

yay thank you for the help

Answer 29

i only got 1 question wrong but its ok

Answer 30

i gtg sleep its late but i really apreciate all the help and kidness
