Question

Write the equation of a circle with a center at 2, -3) and a radius of 1/2
Answers:

(x + 2)2 + (y - 3)2 =1/2

(x + 2)2 + (y - 3)2 =1/4

(x - 2)2 + (y + 3)2 =1/4

(x - 2)2 + (y + 3)2 =1/2

Answer 1

Do you know the formula for a circle?

Answer 2

yes

Answer 3

What is it

Answer 4

I believe the answer is d

Answer 5

(x−h)^2+(y−k)^2=r^2

Answer 6

plug in the coordinates into the formula

Answer 7

Don't forget that your radius is also squared

Answer 8

I did I got D and if the radius is squared it should be D right?

Answer 9

It would actually be C. Like Shizzle said you have to square your radius. so 1/2^2 = 1/4

Answer 10

Ohhhhh ok

Answer 11

C for Close! :) Javi is correct. C for correct, lol

Answer 12

Thank You
