Question

What is the standard form of the equation of the circle with center (-2, -3) and a radius of √2/4?

A) (x - 3)2 + (y - 2)2 = 1/8
B) (x + 3)2 + (y + 2)2 = 1/8
C) (x - 2)2 + (y - 3)2 = 1/8
D) (x + 2)2 + (y + 3)2 = 1/8

Answer 1

Centre of circle = (-2, -3)

Equation of the circle:

( x - ( -2) )² + ( y - (-3) )² = (√2/4)²

(x + 2)² + (y + 3)² = 1/8 (Answer D)
