Question

The formula for the volume of a sphere is V=4/3 pi r cubed. What is the radius of the basketball?

Answer 1

you are given the volume of the ball I assume?

Answer 2

No you are not

Answer 3

well then you can only get the answer in terms of V
you are given that\[V=\frac43\pi r^3\]can you solve this for \(r\) ?

Answer 4

I believe i did but then i just have r\[^{3}\]

Answer 5

1) multiply both sides by 3/4
2) divide both sides by \(\pi\)
3) take the cube root of both sides

Answer 6

i forgot how to do cube root....I ended up with .75V/\[\pi\]=r cubed

Answer 7

just write it out\[\frac3{4\pi}V=r^3\]\[r=\sqrt[3]{\frac3{4\pi}V}\]

Answer 8

Ohhh now that makes sense now! :D you're really smart!
