Thanks.

Sure thing

anonymous · Answer

Do you know how to find the radius for this one..
center (2,5) containing (13,5)

anonymous · Answer

it just says containing and not the radius.. so i'm not sure

jim_thompson5910 · Answer

Find the distance between the two points. Do you know how to do this?

anonymous · Answer

don't you have to subtract them? I forgot which ones go first..

jim_thompson5910 · Answer

The distance from the center to that point will be equal to the radius

jim_thompson5910 · Answer

Close, you subtract them, and then use them in a right triangle to find the length of the hypotenuse
