#### Answer:

#### Explanation:

The general form of a circle centred at

So we first need to find the radius and the centre before we can find the equation.

Length of diameter will be distance between its endpoints.

Therefore the radius

This implies that

The centre of the circle will be the midpoint of the diameter, ie

Therefore the standard equation of this circle will be
