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
