Describe the layers of the sun.

hot gases move up and cool gases sink down appears as a white ring or crown around
the sun at the time of total solar eclipse appears as a red ring around the sun right
before and after the peak of a total solar eclips eregion that energy travels to through radiation
(movement of high-energy particles)region of the sun that is visible from earth where the sun's energy is produced

I'm pretty sure there's a geometry rule for   anyways, if the triangle is equilateral, and the circle is circumscribed, the circle is outside of the triangle.  to find the area, you need the radius.  the radius should be a straight line from the center of the triangle to any of it's points.  draw lines from the center of the circle to each of the triangle points.  draw three more lines from the center to the middle of the sides of the triangle.  you should now have six separate 30-60-90 triangles inside of your original triangle. use your 30-60-90 rules to solve for the radius, then the circumference. 

The correct answer is kettles.
