Answer 1

tp find the volume of a cone u use this forumla
V=πr2h

Answer 2

so we plug this in

Answer 3

The answer is ABOUT 2120.58

Answer 4

Answer 5

So its C, 2120

Answer 6

v=(3.14)(15)^2(9)/3= and we get 2120

Answer 7

@SkylarthekidRS please avoid giving direct answers please..... Thanks :D

Answer 8

Okay! That's what I got! Thanks guys! 4 more?

Answer 9

um sure

Answer 10

I'll be a fan of you all but I'll give the medal to @jagr2713 because she answered first

Answer 11

\[V = 1/3 \pi r ^{2}h\]
\[1/3 * \pi * 15 * 15 * 9 = 2119.5 (\approx 2120)\]

Answer 12

Answer 13

Sorry, I'm new. It took me time to figure out how to insert equations and I had to use Google's calculator :)

Answer 14

Okay, so here's the next one…...

Answer 15

Welcome to OpenStudy @ArsalanAijaz

Answer 16

Thanks :D

Answer 17

A cone has a base radius of 5 centimeters and a height of 18 centimeters.

What is the volume of the cone?

A. 150π cm3

B. 450π cm3

C. 30π cm3

D. 90π cm3

Answer 18

Oh yeah! Lol, welcome, @ArsalanAijaz!

Answer 19

Lemme try it and see what I get first

Answer 20

yea iw as just going to say that

Answer 21

I'm getting 471..

Answer 22

do you know the formula ???

Answer 23

Yea, I think it's V=1/3 pi r^2h

Answer 24

we all did that but i am getting 471

Answer 25

Okay so I got…the same. Maybe we round?

Answer 26

okay then replace
r = 5
and h = 18
and you have to find v right
replace r and h by their values and solve

Answer 27

I was the first. 450's the nearest

Answer 28

lol, i know

Answer 29

Oh no, I got A

Answer 30

none of the answers is correct. but 450 is the nearest

Answer 31

I did it step by step and at the end I divided 450 pi by 3 and I got 150cm3

Answer 32

but doesnt mean 450 can best answer

Answer 33

But 5 times 5(r) in 25 and I multiplied 25 and 18(h) together and got 450. So then I divided it because remember it says one third at the beginning of the formula

Answer 34

what you got @Sexy_einstein

Answer 35

I got A. 150 cm^3

Answer 36

goood to go :)

Answer 37

Great job

Answer 38

Yay! Thanks!!!!!Okay, I hate doing this to you guys but I just have a couple more

Answer 39

A. in3

B. in3

C. in3

D. in3

Answer 43

if you know the formula i'm b\pretty formulas should be on notes
then all u gotta do replace variables by their values thats' all

Answer 47

u use the same foruma i gave you in the beginning

Answer 48

the answer choices are messed up it doesnt show

Answer 49

V=πr2h/3

Answer 50

Oh sorry. It's like this.


A. 28 pi in^3

B. 56/3 pi in^3

C. 196/3 pi in^3

D. 196 Pi in^3

Answer 51

I got c. 196/3 pi in^3

Answer 52

Great job :D

Answer 53

Yay again! Lol. I think I got the hang of it but just to be sure, ca someone check my last two questions after I do them?

Answer 54

ok

Answer 55

Okay, for this one I got 103.6

Use 3.14 to approximate pi, and round answers to two decimal places if necessary.

____ft3

Answer 56

I mean I got 103.67

Answer 57

what are the answer choice

Answer 58

There is none…….unfortunatly.
