The volume of a sphere is 288π ft3. What is the radius of the sphere? Use the formula V = 4/3 πr3 to find your answer.






The radius of the sphere is ______ feet.

Answer 1

Answer: The radius would be six

Step-by-step explanation: Took the test on edg :)

Answer 2

Explanation:

You're just plugging in and doing some algebra.

V = 4/3 πr^3

First plug in what the volume is

288π = 4/3 πr^3

Now let's divide both sides by π just to get it out of the way

288 = 4/3 r^3

Now we can divide both sides by 4/3, which is the same as multiplying by 3/4

216 = r^3

Now just take the cube root, or the third root of both sides. or another way is to bring both sides to the 1/3 power.

6 = r

And there's you're answer. if there's a step you don't understand let me know.
