Answer 1

When finding the square root of any number there is is the + and - root when using this information to solve a problem only the positive root is used you can't solve involving measurements using the - root hope this helps

Answer 2

Given: Square root of 25 .i.e.,
`√(25)`

When we find the
`√(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
`√(25)` .i.e, +5 because Radius of circle should be a positive value as it is a Length.
