Answer: sqrt(85)/2

Explanation:

Remember that the length of the diameter is twice that of the radius.

The first step would be finding the distance between the two points using the distance formula
$\sqrt{(x_2 - x_1)^(2) + (y_2 - y_1)^(2)$ .

The distance of diameter =
√(85)

The distance of the radius would be half that, so
(√(85))/(2)
