Numbers can be estimated by approximating them. So, we need to approximate [tex]\sqrt{71}[/tex] to the nearest integer to get its estimate of the radius in the nearest foot.
The radius to the nearest foot is 8ft
Given that
[tex]r = \sqrt{71}[/tex]
To calculate the radius, we simply determine the square root of 71
[tex]r = 8.42614977318[/tex]
Approximate to the nearest integer
[tex]r = 8[/tex]
Hence, the radius of the circle to the nearest foot is 8ft.
