Riia

To find the radius , we check out the end points of the diameter, then we find the length of diameter and then we do half of it to find the radius .

Here the endpoints of the diameter are (-1,5),(-1,-7).

Length of diameter = 5-(-7) = 12

Therefore radius = 12/2 = 6 units

So the radius of the given circle is 6 units .

we know that radius of a circle is the half of the value of diameter

we have given a circle in graph

first we need to find the diameter of this circle

as we extends from left corner to right corner there will be 12 units

which is diameter

then radius=diameter/2=12/2= 6 units.
