Ok, so I have a triangle of sides 330, 270, and 240, and there is a circle of maximum area within this triangle. This circle has an area of 18200, and thus a radius of 76.11333608. How can I find the equation of this circle?

In response to what has been said, my question really is if I am able to find those co-ordinates of the center through the data that I know already.
In simple terms, can I find where the centre of that circle is from what I know?

Where's the origin? If you have a radius, you can easily just put the origin at the center of the circle.
x^2 + y^2 = (76.11333608)^2
If you want it solved for y:
y = sqrt(76.11333608^2 - x^2)

You can't. All you have is the length of the sides and the radius of the circle (or rather radius^2). For an equation you need co-ordinates. Where, exactly is the triangle located, and hence where exactly is the centre of the circle? If you know the centre of the circle to be some point (h,k) then equation can be easily written down in standard form.

Hexagons and small circles interior a huge circle may be arranged further, however the circles does no longer %. mutually and take up each and every of the area like hexagons might. Pentagons are used to %. the area of a dodecahedron floor, and on a around floor, like a soccer ball, pentagons are used on the side of hexagons in geodesic designs.

you need at least two coordinates. Here is what i can give you
