Acircular table top has an area of 324 square inches. which measurement is closest to the radius of the table top in inches?

So work the problem backward.

Normal way to solve problem

x^2 x 3.14 = area

Backward

324 / 3.14 = 103.184 
= 10.157

The answer is 10.157

But let's plug in the numbers to make sure

10.157^2 x 3.14 = 323.9.. or the rounded answer

(If you want an exact answer you have to throw it through a calculator)
