WILL FAN AND MEDAL ONE EASY GEOMETRY QUESTION!
Which of the following is the equation of a circle with a radius of 2.5 and its center at (4, –3)?
(x – 4)2 + (y + 3)2 = 2.5
(x + 4)2 + (y – 3)2 = 2.5
(x – 4)2 + (y + 3)2 = 6.25
(x + 4)2 + (y – 3)2 = 6.25

Answer 1

What do you think?

Answer 2

@TwiztTiez , I think its option 2?

Answer 3

I don't think so

Answer 4

@TwiztTiez I dont know how to solve it, im stuck:( my second guess would be option one

Answer 5

Remember the general circle equation:
(x - h)² + (y - k)² = r²

Where:
h = x coordinate of the vertex
k = y coordinate of the vertex
r = radius

Given: radius of 2.5
Means: r = 2.5

Given: center at (-4, 3)
Means: h = -4
Means: k = 3

Plug these into the general equation.
(x - h)² + (y - k)² = r²
(x - -4)² + (y - 3)² = (2.5)²
(x + 4)² + (y - 3)² = 6.25

ANSWER: D. (x + 4)² + (y - 3)² = 6.25
