Question

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

(4/3) cubic inches
(91/3) cubic inches
(364/3) cubic inches

Answer 1

To find the volume of the space between two concentric spheres, you would calculate the volume of both spheres and then subtract the volume of the smaller sphere from the volume of the large sphere. Hint: Volume of a sphere\[V=\frac43\pi r^3\]

Answer 2

i did that twice and i dont know y im not getting the correct answer

Answer 3

What answer are you getting?

Answer 4

im getting 6070pi

Answer 5

\[V=\frac43\pi (6)^3-\frac43\pi (5)^3=\frac43 \pi (6^3-5^3)=\frac43\pi (216-125)=\frac43\pi (91)=\frac{364\pi}{3}\]

Answer 6

Did you copy the answer choices incorrectly? I think there might be a π missing.

Answer 7

oh yea there is a pi missing and thank u so much ur awesome thast y im ur fan

Answer 8

you're welcome.
