Find the volume of a sphere that has a radius of 6 feet

I think the answer for this question is 18.84 but I forgot if you needed the radius or diameter to get the area of a circle of it's the diameter it's 37.68

Volume: 905 (units^3)

Step-by-step explanation:

Let us substitute the value of the radius into the well known formula of a sphere:

Volume of a Sphere: (4/3 * π * r^3)

* Where r acts as the radius and π is well, the constant

Let us first substitute while keeping π in it's standard form:

4/3 * π * (6) ^3 = 4/3π * (216) = 864/3π = 288π

Now let us substitute π as it's simplified, 3.14 value:

288 * (3.14159265 ...) = (Around) 905 units^3
