Need help please and thank you

Given:

Center (3.2, -2.1)

Radius = 4.3

To find:

The equation of the circle.

Solution:

The standard form of an equation of a circle:

where r is the radius and (h, k) is the center.

Here (h, k) = (3.2, -2.1) and r = 4.3

Substitute this in the standard form.

The equation of the circle is .

∞ this is your sign
