The radius is 4
the equation of a circle is (x-h)^2+(y-k)^2=r^2
in this case, 16=r^2
so r=4

16^2 is the radius, so 16 squared is 4. Therefore the radius is equal to 4

2008 population of wyoming was counted as 532,668 people. what is a reasonable estimate of the population of wyoming?

Snezhnost [94]

The smaller is the rounding factor, the more accurate the estimation is

532668 rounded to the nearest ten is 532670
532668 rounded to the nearest hundred is 532700
532668 rounded to the nearest thousand is 533000
532668 rounded to the nearest ten thousand is 530000
532668 rounded to the nearest hundred thousand is 500000

We can use either 532700 or 533000 as a reasonable estimate because these values don't give much difference to the original value
