How do I find the volume of a sphere when I only have the circumference?

Step-by-step explanation:

Circumference of a circle is C = 2π r.

Volume of a sphere is V = 4/3 π r³.

Use the circumference to find the radius.  Then use the radius to find the volume.

Or, you can find volume as a function of radius:

r = C / (2π)

V = 4/3 π (C / (2π))³

V = 4/3 π (C³ / (8π³))

V = 1/6 C³ / π²

V = C³ / (6π²)

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
