Geometry Spheres

Answer 1

@OM14forever

Answer 2

no actually 3037.95 in^3

Answer 3

Okay so it looks like your first calculation was correct

Answer 4

it was?

Answer 5

900.13 in^3?

Answer 6

im confused

Answer 7

Okay I'm gonna start over

Answer 8

So the formula that you use I will post below

Answer 9

\[\frac{ 4 }{ 3 }(3.14)r ^{3}\]

Answer 10

ok

Answer 11

So as you probably know...... r is the radius, which is half the diameter. Since the diameter of the whole sphere is 18 the radius would be half of that, which is 9. If you plug 9 into the formula what do you get?

Answer 12

Outer Layer: 3052.08
Core: 14.13

Answer 13

mmmmm..... Maybe but I don't think so....

Answer 14

Use the numbers from the picture you posted

Answer 15

\[3053.63-14.14=?\]

Answer 16

That's what I calculates at least.....

Answer 17

those numbers used the full pi, but the problem wants me to only use 3.14. I have had several times in the past with similar problems where i use pi instead of 3.14 and i get it wrong

Answer 18

@Loser66 Please help

Answer 19

I'm confused by what you said....

Answer 20

The problem says use 3.14 to approximate. If I use the full \[\pi\] it wouldn't be the same as what the system has stored as the answer

Answer 21

Oh wait nvm I get it

Answer 22

because 1.5 times pi is 14.14 but 1.5 times 3.14 is 14.13

Answer 23

you're correct..... let me recalculate

Answer 24

ok

Answer 25

3052.08-14.13=?????

Answer 26

3037.95

Answer 27

So yes your answer above is correct

Answer 28

I'm going to take another look at the other questions I helped you on to make sure that they are correct...

Answer 29

yeah i went back to the one before this and corrected it

Answer 30

i hope

Answer 31

So sorry I was calculating online not on paper

Answer 32
