Circles in an equilateral triangle.

Click For Summary
SUMMARY

The discussion centers on calculating the ratio of the area of three circles inscribed within an equilateral triangle to the area of the triangle itself. The relevant formulas mentioned include the area of a circle (πr²), the area of a triangle (1/2(b)(h)), and the specific formula for the area of an equilateral triangle (√3/4 * a²). Participants emphasized the need for clarity in the problem statement, confirming that three circles are inscribed within one triangle.

PREREQUISITES

Homework Statement



Three triangles are placed into a circle; The vertices of the triangle are tangential to each circle. How do you find the ratio of the area of the circles to that of the triangle?

Homework Equations



pi r^2, 1/2(b)(h), sqrt3/4 * a^2 (2r^2).

The Attempt at a Solution



Tried drawing lines within, tried using double angle formulae, tried a lot of different things, but I still can't make that logical jump. Help? :(

Your first sentence implies there is only one circle and three triangles. The question implies there is more than one circle but only one triangle. It sounds a bit vague to me.
 
Whoops sorry. I meant.

"Three circles are placed into a triangle.". That's it. LOL
