Question

What is the radius of a circle whose endpoints of a diameter are A(-4, 14) and B (2,8)​

Answer 1

9514 1404 393

Answer:

3√2

Explanation:

The length of the diameter is given by the distance formula:

d = √((x2 -x1)² +(y2 -y1)²)

d = √((2 -(-4))² +(8 -14)²) = √(36 +36) = 6√2

The radius is half the diameter, so the radius of your circle is 3√2.
