D. 81

Answer :

Considering a circle whose equation is (x + 6)² + (y + 8)² = 9. The radius of the circle is 3 units

How to determine the radius of the circle

Information given in the question

Circle F is represented by the equation (x + 6)² + (y + 8)² = 9

Equation of a circle is given as

(x - h)² (y - k)² = r²

The equation of the circle is written in standard form is sown above comparing the equation with the given question gives

rewriting the equation

(x + 6)² + (y + 8)² = 9

(x + 6)² + (y + 8)² = 3²

comparing shows that r = 3
