Question

Can someone please help me i just don't get it?
The volume of sphere w is approximatley 47.92π in^3. If the square factor from where w to x is 3 , what is the diameter of sphere x.
A.) = 9.9 in
B.)= 19.8 in
C.)=143.75in
D.)=4.4in

Answer 1

\[V = {4 \over 3} \pi r^3\]

Answer 2

so its C

Answer 3

Right?

Answer 4

and can you explian

Answer 5

you there ?

Answer 6

i am, yeah.. and I don't think it's C.

Answer 9

katie - i'm not telling you wheter it's right or not, cause you just want to have the correct answer and be lazy. I understand that - i hate maths, too!
But please also understand that i'm not going to support you with that strategy, cause it wont work out in the end.

I will however try and explain everything, IF you try to do it yourself and tell me/us where you got stuck etc etc...

Answer 10

okay well can you explain it to me?

Answer 11

well the formula for calculating the volume of a sphere is
\[V = {4 \over 3} \pi r^3\]
now look at the problem and tell me, what do you already know and what do you want in the end?

Answer 12

to find x of 3

Answer 13

What's x ?

Answer 14

3
