The radius of a circle whose equation is (x + 5)^2 + (y - 3)^2 = 4^2 is mathematically given as
r=4 units, Option B is correct
What is the radius of a circle whose equation is (x + 5)^2 + (y - 3)^2 = 4^2?
Question Parameters:
a circle whose equation is (x + 5)^2 + (y - 3)^2 = 4^2
Generally, the equation for the circle is mathematically given as
(x + 5)^2 + (y - 3)^2 = 4^2
Therefore, its standard form of a circle equation is
(x-h)^2+(y-k)^2=r^2
In conclusion, Comparing both equations
r^2=4^2
r=4
