Help. Find the length of the diameter of a sphere with a volume of 143.8 miles^3

Answer 1

is ther like a formula or something :/

Answer 2

5.86 miles 3.25 miles 6.5 miles 11.72 miles

Answer 3

The Volume of a sphere = (4/3)*pi*r^3
The volume is given which is 143.8
===
Don't Forget that , D (diameter) =2r(radius)
Can you continue ?

Answer 4

6.5 miles then?

Answer 5

Hmm,Let's See
143.8=4/3 * (3.14)*r^3
r^3=3.25 miles , d = 2r =2(3.25)=6.5 miles So yea !

Answer 6

Of course.. it all makes sense now.. how could I have not thought of that before.. thank you wise one. Here, have a cookie. (*.*.*)

Answer 7

Ty for the cookie :)
