I am given this formula (7/4)pi r^3 where pi is 4.5678, and I am given two values in centimeters 7.10 cm and 7.00 cm.
Am I suppose to replace the centimeters in r^3 and multiply it with (7/4) and pi?

Ok an esphere has a ratio of 7.10 cm and the other esphere has a ratio of 5.00 cm. Which is the difference in volume (ml) between the two espheres? The volume of the esphere is c= (4/3) pi r^3, where pi is 3.1416.

Ok yes, I wrote the question incorrectly on purpose, I don't want to get caugh hehe.

the data is completely different from what I have here, I just want to get an idea, to answer it myself.

yes. The r is the radius. So itappears you are trying to calculate the volume of something. r=7.1 or 7 depending on which one you are using. If you are trying to calculate the volume between those two radius', the formula would be (7/4)pi(r1-r2)^3

You would have to give a little more information, so that we have the context of the problem. From your information it probably is substitute in the 7.10 or 7 in for r. I am not sure where you are getting pi is 4.5678

You replace the number as 'r'. So you would cube it (r x r x r) and multiply it by 7/4 pi.
But I am thinking this is a bogus question, since pi is not 4.5678.
