we know that
The circumference of a circle is equal to
where
D is the diameter of the circle
we have
substitute and solve for D
Find the radius r
-----> the radius is half the diameter
Ok so for Letter F the answer is going to be x=2 or y=-2 depending if you’re trying to find x or y.

x =(10+√140)/2=5+√ 35 = 10.916
or:
x =(10-√140)/2=5-√ 35 = -0.916
