Question

a sphere has a 3m diameter. what is its volume to the nearest hundredth?

Answer 1

The formula for the volume of a sphere is:

V = (4/3) * pi * r^3 where r is the radius of the sphere. @carolinagrl

Answer 2

use the volume formula!

Answer 3

Directrix has put the formula for you just put the value of (r)

Answer 4

The radius is 3/2 because the radius is one-half the diameter.

V = (4/3) * pi * r^3
V = (4/3) * pi * (3/2)^3

Crank this out and let us know what you get.

Answer 5

where did you get the 4/3?

Answer 6

?
