Answer 1

Well the formula for volume of a cone is

\[V = \frac{ 1 }{ 3 } \pi r^2 h\]

so plug in your numbers and solve for 'V'

Answer 2

wahh? i confuzzled

Answer 3

Lol okay...the question wants you to find the volume of a cone with radius 6 and height of 5...and to use 3.14 for pi....so with the equation I wrote above...and putting these numbers in we get...

\[V = \frac{ 1 }{ 3 } \times 3.14 \times 6^2 \times 5\]

and solve that

Answer 4

how do you do the 1/3 x 3.14

Answer 5

Here it might be easier if I write it as

\[V = \frac{ \pi r^2 h }{ 3 }\]

so

\[V = \frac{ 3.14 \times 6^2 \times 5 }{ 3 }\]

Answer 6

erm i got 559.70 i did it so wrong

Answer 7

Hmm let's do it out

\[V = \frac{ 3.14 \times 6^2 \times 5 }{ 3 }\]

\[V = \frac{ 3.14 \times 36 \times 5 }{ 3 }\]

\[V = \frac{ 565.2 }{ 3 }\]

\[V = 188.4\]

Did that make sense?

Answer 8

All except how to multiply 3.14x36

Answer 9

I get you got 36 by squaring 6 (6x6) i just dont know how to multiply pi

Answer 10

Well I just did it out on paper really....because we are only using 3.14 for pi...not the actual value of pi *which we don't know entirely but still*

Answer 11

Lol crappy drawing but still :)

Answer 12

I didnt get a drawing

Answer 13

Still nothing? wow first time that happened

Answer 14

it's there now

Answer 15

oh okay i get it now as far as the pi multiplcation

Answer 16

perfect :) I hope it makes sense :)

so to finish that for your equation *since that is just 3.14 times 36...

you multiply the 113.04 times 5 to finish what's in the numerator...

This comes out to 565.2

Now the only thing left to do is divide that 565.2 by the 3 that is in the denominator...

That's where I got the 188.4 from

Answer 17

purrfect thanks for your help for real!!!

Answer 18

No problem Ryleigh :)

*remember you from your old account lol*
