pi r cubed Where are the radius of the sphere
- 00:42
Will be careful We're given the diameter right here where
- 00:45
it says eighteen meters but we need to take that
- 00:48
number and slice it in half before we proceed Eighteen
- 00:52
cutting half his nine So the radius is nine and
- 00:55
all righty Well now we have four thirds pi times
- 00:59
Nine cube Well nine cubes is let's See ten times
- 01:03
they want Seven hundred twenty nine The four thirds of
- 01:07
seven hundred twenty nine is or some one hundred twenty
- 01:10
nine times for is two thousand sixteen divided by three
- 01:14
on her nine hundred seventy two So the volume of
- 01:17
the sphere is nine hundred seventy two pi cubic meters
- 01:22
option a all right That's Probably a little too small
- 01:26
to be a planet and a little too big to
