Question

State the radius of the circle of the equation

(x+3) ²+(y+3) ²= 5
Round your answer to the nearest hundredth.

Answer 1

radius = √5 = 2.24 to nearest hundredth.

Explanation:

(x + 3)^2 + (y + 3)^2 = 5 comparing with the standard form

(x - h)^2 + (y - k)^2 = r^2

-h = 2 so h = -3, -k = 3 so k = -3.

r^2 = 5 so r = √5.
