I absolutely NEED help with this homework. Please help me. I am such confusion. I will love you forever, and whoever can give me the correct answer first gets a free drawing gaiz!
No really, I am begging you. On my knees. This is due Friday the 24th and I am so incredibly confused.
Here's a question-
Consider a rectangle inscribed in a circle with a radius of R. What are the possible perimeters for the rectangle?
I think it involves higher-lever math that what I'm in. ANYBODY KNOW HOW TO FIND THIS?! ANYONE?!

Ten might know, because I don't. /only a freshman
Hmmm...there's nothing special about the rectangle despite that it's in a circle? Sounds like it's the normal way - you know, count up the sides' lengths. Unless the only information they give you is R and you're only supposed to find /how/ to get the perimeter...in that case you'd need to write an algebraic expression...hum...I don't know.

ANYBODY KNOW HOW TO FIND THIS?! ANYONE?! Hmmm. A picture would make this easier. If the circle is inscribed in the rectangle, does that mean that all the sides of the rectangle are tangent to the circle (the circle touches the rectangle at four points)? If so, then you know that the radius of the circle must be the same as half of one rectangle side, right? |

The rectangle is inside the circle, dawg.

/misread that. /also, not a dog.
Oh. Okay.
In that case, the distance from the center of the circle to one of the rectangle's points would be the same as the radius, no? Is there a picture to this, or is it just a word problem? Anyway, the diameter of the circle, diagonal from rectangle corner to corner, should split the rectangle into two triangles, and there might be some triangle formula you could use to determine the side lengths that way, from which you can then find perimeter.

Hm, I don't really know, but each long side of the rectangle is 2R, right?

I don't know. I'm in geometry, so maybe I'll learn that later this year Dx
