Step-by-step explanation:

The general equation of a circle has the form:

Where r is the radius of the circumference.

In this problem we have the circle with equation

1) The intercepts with the x-axis we find them doing y = 0 and solving for x:

The intercepts with the y-axis we find them doing x = 0 and solving for y:

The 4 interceptions are:

2) The radius is:

3) The area of a circumference is:
