Question

A circle has its center at (-1, 2) and a radius of 3 units. What is the equation of the circle? (1 point)
Select one:
a. (x - 1)2 + (y + 2)2 = 3
b. (x + 1)2 + (y - 2)2 = 3
c. (x + 1)2 + (y + 2)2 = 9
d. (x + 1)2 + (y - 2)2 = 9

Answer 2

standard form of equation of circle :

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

center = \(\large (h,k)\)
radius = \(\large r\)

Answer 3

you're given, center = \(\large (h,k) = (-1, 2)\)
and radius = \(\large r = 3\)

simply plug them in the equation, you're done.
