The diameter of a sphere is 4 centimeters. Which represents the volume of the sphere?

32/3 pi

Step-by-step explanation:

The volume of the sphere is 4/3 pi r^3.  r=2 because it is 1/2 of the diameter.  Now just plug it into the equation.  4/3 pi 2^3= 4/3 pi 8= 32/3 pi

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
