Question

Write the equation of the circle graphed below.

Answer 1

Answer:

As shown in picture, this circle has radius 1.5 and passes (0, 1.5)

=> According to the general form of equation of circle that has radius r and passes (a, b): (x - a)^2 + (y - b)^2 = r^2, we have:

x^2 + (y - 1.5)^2 = 1.5^2

<=>

x^2 + (y - 1.5)^2 = 2.25

Hope this helps!
