What is the radius of a circle whose equation is (x - 7) 2 + (y - 10) 2 = 4? 2 units 4 units 8 units 16 units

2 units

Step-by-step explanation:

The radius of a given equation of the circle is 2 units because the general equation of a circle for two-dimension is:

(x-a) ² + (y-b) ² = r²

where r is the radius of a circle

and, (a, b) is the center of a circle.

For the given equation of a circle, we have center (7,10) and the radius is 2 units.

Thus, the First option is correct only and not others.

A. 2 units
