PLZ HELP ASAP FEATURES OF A CIRCLE FROM ITS STANDERED EQUATION

Answer 1

The center of a circle of the form:


`(x-a)^(2)+(y-b)^(2)=r^(2)`

is (a, b) and its radius is r.

Comparing the given equation of circle we can write:

a = 20
b = 0.05
r² = 81

This means the center of the circle is (20, 0.05) and the radius of the circle is 9.
