Find the volume of the sphere. Give the answer in terms of pi and rounded to the nearest cubic foot.

Inessa05 [86]

Hi there!

The formula for the volume of a sphere is V = 4/3(pi)(r^3). Using this formula, we can plug in what we know and solve.

WORK:
V = 4/3(pi)(10^3)
V = 4/3(1000pi)
V = 4000pi/3 or 1333.3 pi
V also = 4188.8

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
