Write an equation of the circle with center (-8,4) and diameter 6 .

Mathematics

ra1l [238]4 years ago

Answer:

(x+8)^2 + (y-4)^2 = 3^2

or

(x+8)^2 + (y-4)^2 = 9

Step-by-step explanation:

The diameter is 6, so the radius would be d/2 =3

The equation of a circle is

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

where (h,k) is the center and r is the radius

(x- -8)^2 + (y-4)^2 = 3^2

(x+8)^2 + (y-4)^2 = 3^2

or

(x+8)^2 + (y-4)^2 = 9

Solve for x <img src="https://tex.z-dn.net/?f=%20S%3D7%20x%5E%7B2%7D%20" id="TexFormula1" title=" S=7 x^{2} " alt=" S=7 x^{2} "
il63 [147K]
S = 7x^2....divide both sides by 7
1/7s (same as s/7) = x^2...now take sqrt of both sides
(+ - ) sqrt 1/7s = x
