##### 2 Answers

#### Explanation:

If the diameter is

then center is at

and

the radius is

The general equation of a circle

with center

In this case we have

#### Explanation:

Formula for the eqn. of a circle having

Accordingly, the reqd. eqn. is

i.e.,

or,

**Aliter :-**

Extremities of a diameter are

Centre, being midpoint of diameter, we get the centre

Radius = Distance between the Centre & any end point of given diameter

Hence the eqn.
