Question

The points ​(​-4,​-3) and ​(2​,4​) are the endpoints of the diameter of a circle. Find the length of the radius of the circle.

Answer 1

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)`
