Radius- 5
The radius is half, so if you want to find the radius, you have to see what if half of the diameter, which is 10. So 10 divided by 2 is 5 which is the radius. Easy.
√16=4
Hope i could help. -\(-_-)/-
The quotients are equal because they both go in the same number of times. The second pair of quotients just have an extra 0 at the end which just changes the place value of the number.
You only need to look at the y intercepts.
-11 - -7 is -4, but you can't have a negative distance so it's just 4
