If the volume of a sphere is 576 pi cubic units what is the radius

If the volume of a sphere is 576 pi cubic units, then the radius is 7.56. I arrived to this answer through solving first what is 576 (π) which led me to the answer 1808.64. Then I solved for the radius through deriving the formula of a volume of a sphere to finding the radius. Thus, the final ansewr is 7.56 units.
