Question

What is the volume of a cone with a diameter of 18 cm and a height of 10 cm?
Use 3.14 for pi. Round your answer to the nearest tenth

Answer 1

\[\huge~\rm~\bf~V=\pi~r^2\frac{ h }{ 3}\]

Answer 2

To find the radius divide the diameter by 2
18/2=?

Answer 3

9

Answer 4

Good
\[\huge~\rm~\bf~V=(3.14)(3^2)(\frac{ 10 }{ 3})\]

Answer 5

3^2=?

Answer 6

9

Answer 7

Good
Now just solve for V
Good
\[\huge~\rm~\bf~V=(3.14)(9)(\frac{ 10 }{ 3})\]

Answer 8

dont we have to divide 10 by 3?

Answer 9

Yeah

Answer 10

I suggest using a calculator for this part

Answer 11

wait let me see

Answer 12

94.2? @pooja195

Answer 13

That's correct

Answer 14

thank you :)

Answer 15

yw ^_^

Answer 16

Wait hold up

Answer 17

I messed up the radius is 9 not 3 >.<
\[\huge~\rm~\bf~V=(3.14)(9^2)(\frac{ 10 }{ 3})\]
\[\huge~\rm~\bf~V=(3.14)(81)(\frac{ 10 }{ 3})\]
Now solve for V

Answer 18

847.8?

Answer 19

There we go ok yes thats correct

Answer 20

can you help me on one more:)

Answer 21

ok :) post it ^_^

Answer 22

⦁ A cone has a radius of 6 inches and a height of 11 inches. What is the volume of the cone?

Answer 23

\[\huge~\rm~\bf~V=\pi~r^2\frac{ h }{ 3}\]
Same formula
\[\huge~\rm~\bf~V=(3.14)~(6)^2(\frac{ 11 }{ 3})\]
solve for v

Answer 24

414.48?

Answer 25

i got
414.69 but it doesnt really matter :P

Answer 26

Well done =)
