How many cubic feet are in a 30 foot diameter sphere?

Answer 1

None or infinitely many, depending upon your view of the second and third dimensions of a linear length.

Or to put it another way:

Cubic feet measure volume, whereas

inches measure length

They measure different things and it makes no sense to ask how much volume in a length.

Answer 2

Volume of sphere = 4/3*pi*radius3

Volume = 4500*pi cubic feet

Answer 3
