(704)/3 cubic ft.
(34,496)/3 cubic ft.
(4,312)/3 cubic ft.

Answer 1

The volume of a sphere is given by \[V=\frac43 \pi r^3\] where r is the radius.

Answer 2

i did that and got 2003 as my answer

Answer 3

What did you use for r?

Answer 4

i used 7

Answer 5

\[V=\frac43 \pi r^3= \frac{(4)(3.14)(7^3)}{3}=\frac{4308}{3}\]

Answer 6

oh i forgot the 4 on the top but thanks ur the best

Answer 7

you're welcome
