Given that the radius of the incricle is 1, what is

24. the radius of the circumcircle

25. the circumference of each circle

26. the area of each circle

**Reiny**, Thursday, May 15, 2008 at 7:01pmthe two circles would be concentric, (have the same centre)

Draw the triangle by joining a vertex of the triangle to the centre of the incircle.

Notice that we now have a 30,60,90 triangle with the side across from the 30º equal to 1.

So the other two sides are √3 and 2, with 2 they hypotenuse.

So the inner circle has a radius of 1 (that was given)

and the outer circle has a radius of 2

You should now be able to do the rest of the question.
