Answer 1

Answer:

Given: Square root of 25 .i.e., $\sqrt{25}$

When we find the $\sqrt{25}$ . we get 2 answers that are +5 , -5

As, $(+5)^2 = 25$ . Also $(-5)^2=25$

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