iDentify the equation of the circle that has its center at (-27, 120) and passes through the origin A. (x−27)2+(y+120)2=123 B. (

melomori [17]

The equation of a circle is given in the form $(x-a)^2+(y-b)^2=r^2$ , where

(a, b) is the centre of the circle
r = radius

We have the centre of the circle (-27, 120)
We can work out the radius by modelling the radius as the hypotenuse of a triangle as shown in the diagram below

$r^2=27^2+120^2$
$r^2 = 15129$

The equation of the circle is

$[x-(-27)]^2+[y-120]^2=15129$
$[x+27]^2+[y-120]^2=15129$

Any idea ? I need help

trasher [3.6K]

Use the Pythagorean Theorem:
a^2 + b^2= c^2

a= one side= 68 mi
b= second side= 80 mi
c= hypotenuse= Greenville to Columbia mi

a^2 + b^2= c^2

68^2 + 80^2= c^2
square each number

4,624 + 6,400= c^2

11,024= c^2
take square root of both sides

104.995 mi= c

ANSWER: The distance from Greenville to Columbia is 104.995 miles (rounded to 105 miles).

Hope this helps! :)
