Question

Two concentric spheres have radii of 5" and 6". Find the volume of the space between them.

Answer 1

find the volume of the larger radius circle, and subtract it from the volume of the lower

Answer 2

how do you do that?

Answer 3

(4/3)(pi)(r^3)= volume

Answer 4

still dont get it at all

Answer 5

i suck at math lol

Answer 6

\[V=(4/3){\pi}r^3\]
\[V _{6"} = (4/3)\pi(6)^3=(4/3)\pi(216)=288\pi\]
\[V _{5"} = (4/3)\pi(5)^3=(4/3)\pi(125)=(500/3)\pi\]
\[V _{between} = V _{6"} - V _{5"} = \]

Answer 7

Hint: \[288\pi = (3*288\pi)/3\]
