Answer:
Step-by-step 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.
