Answer:
Step-by-step explanation:
Given
Let the number be x
So:
Required
Using trial and improvement, find x
This implies that we keep guessing the values of x until we get a value that match the equation.
Let
So, we have:
Take the square root of 625
Let
So, we have:
Take the square root of 729
At this point, we can conclude that x is approximately 729 because
So:
The best way to justify which answers are correct are to calculate the circumference and the area for each of the circles with the given radii. I organized this information into a chart.
Circumference | Area
1/2 3.14 0.785
1 6.28 3.14
1 1/2 9.42 7.065
2 12.56 12.56
2 1/2 15.7 19.625
The first three choices will result in a numerical value for the radius that is smaller than the area.
