Question

The center of a circle is at the origin. An endpoint of a diameter of the circle is at (-3, -4). How long is the diameter of the circle?


5
10
25

Answer 1

What's the distance between the given point and the origin?

Answer 2

(0,0) is the center , thats simple
count the distance between the two points ,
\[distance = \sqrt{(-3 - 0 )² + ( -4 - 0 ) ²}\]
\[distance = \sqrt{9 + 16 }\]
\[distance = \sqrt{25 }\]
\[distance = 5\]

Answer 3

\[\sqrt{(x2-x1)² + (y2- y1)²}\]

Answer 4

Thank you!!!!!!!
