Find the radius of a circle whose diameter has endpoints (-3,-2) and K(7,8).

Given:

End points of the diameter are (-3,-2) and (7,8).

To find:

The radius of the circle.

Solution:

Distance formula:

End points of the diameter are (-3,-2) and (7,8). Using the distance formula, the length of diameter is

So, the diameter is units.

We know that, radian of a circle is half of its diameter. So,

Therefore, the radius of the circle is units.
