Will give a medal~

Short version: I am unsure how to graph a circle with an equation.

Long version:
So here was the problem (this is the last question of many so there's some stuff out of context)

Imagine the center of the Ferris wheel is located at (0, 0) on a coordinate grid and the radius lies on the x-axis. Write an equation of a circle for your Ferris wheel, and sketch an image of what your Ferris wheel would look like on the grid.

My answers:
Well the radius is 75. So this is what I got for the equation:
x^2 + y^2 = 75^2

But how do I graph this equation? Like how do I draw it

Are you sketching it freehand, or do you have a compass?

anteater · Answer

I prefer to use graph paper for math problems, and if I were to graph this I would draw my x and y axes, use the origin (0,0) as my center, then probably set the scale of the graph to be 1 square = 25 feet (or meters, or whatever unit they are using).

If I were freehanding it, I would then mark the points (75,0); (0,75); (-75,0) and (0,-75) and try to draw a circle with those points lying on it.

anteater · Answer

If I had a compass, though, I would simply mark (75,0), then use the origin and that point to set the compass, center the compass on (0,0) and draw a circle. :)
