Answer:

Given: Square root of 25 .i.e., [tex]\sqrt{25}[/tex]

When we find the [tex]\sqrt{25}[/tex] . we get 2 answers that are +5 , -5

As, [tex](+5)^2 = 25[/tex] . Also [tex](-5)^2=25[/tex]

but while selecting value for radius we choose positive value of [tex]\sqrt{25}[/tex] .i.e, +5 because Radius of circle should be a positive value as it is a Length.
