The radius of a sphere is 6 units.

skad [1K]

Answer: Four-thirdsπ(6)³

Step-by-step explanation: The formula for the volume of a sphere is attached in the image down below.

Notice that two of the options listed have <em>three-fourths</em> but we use <em>four-thirds </em>to find the volume of a sphere. This means that we can eliminate the 1st and the 3rd option.

Now, we will multiply that by π and then by the radius cubed which is also written as 6³. This means that our answer would be the second option.
