Question

Graded Assignment: Volume Part 2 And I need help with it

Answer 1

I need help and supie said that your smart

Answer 2

\(\text{Volume of a cone} = \pi r^2 \dfrac{h}{3}\)

Answer 3

Ok that makes sense Thank you

Answer 4

so they told us radius = 6
and height = 8

can you put those numbers in place of r (for radius) and h (for height)

Answer 5

yes

Answer 6

Like on the picture?

Answer 7

In the formula

Answer 8

nice drawing!

so let's plug it in

\(\text{Volume of a cone} = \pi r^2 \dfrac{h}{3}\)

\(\text{Volume of a cone} = \pi \times (6)^2 \times \dfrac{8}{3}\)

can you multiply the numbers?

Answer 9

Thanks! Um the formula is V= 1/3 pi r2h

Answer 10

that's correct

Answer 11

Yeah I do not know how to multiply that? lol

Answer 12

okay, step by step

what is 6^2
that's the same thing as 6 * 6 =

Answer 13

Oh ok

Answer 14

36

Answer 15

so we go from

V= 1/3 pi r^2 h

V = 1/3 pi * (6)^2 * 8
V = 1/3 pi * 36 * 8

what is 36 * 8 =

Answer 16

288

Answer 17

so now we have

V = 1/3 pi * 36 * 8

V = 1/3 * pi * 288

now the first question wants an exact answer so that means we don't change pi to 3.14. We just leave it as pi

so all we have left to do is

1/3 * 288 = ?

Answer 18

863

Answer 19

uh oh

careful there

it's 1/3 not 3



so multiplying by 1/3 is the same as dividing by 3

Answer 20

So it's? =288
----
3

Answer 21

yes

Answer 22

what do you get when you divide

Answer 23

so divide 288 and 3

good job - like always - congrats !!!

Answer 25

\(\color{#0cbb34}{\text{End of Quote}}\)

yes

Answer 26

ok

Answer 27

96

Answer 28

V = 1/3 * pi * 288

so we get our final answer for part A

V = 96\(\pi\)

for the second part, we just use 3.14 for pi

so what is 96 * 3.14

Answer 29

It just keeps going Hehe

Answer 30

yes which is why they asked you to just use 3.14

Answer 31

3.01.44

Answer 32

lol

Answer 33

did you mean 301.44?

Answer 34

yah Thanks lol

Answer 35

good job :)

Answer 36

Wait that was the answer?

Answer 37

V=301.44

Answer 38

yes that's the answer to the second part

Answer 39

Thank you!

Answer 40

You're welcome!
