The circle shown is centered at the origin and contains the point (-4, -2). What is the length of the diameter of the circle? Round your answer to the nearest hundredth

Step-by-step explanation:

Equation for circle centered at origin:

x² + y² = r².

Therefore r² = (-4)² + (-2)² = 20, r = √20.

Hence d = 2r = 2√20 = 8.94 (2d.p.)
