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

This endpoint is at -3 in x and -4 in y.
You can use pythagoras to find the answer
( -3)^2+(-4)^2= radius^2
When you get the radius value, multiply it by two and that will be your diameter
