Question

Circle Forumla for a feris wheel

Answer 1

Check the picture below.

so we can say, what's the equation of a circle with a center at (0 , 136) with a radius of 120?

`\textit{equation of a circle}\\\\ (x- h)^2+(y- k)^2= r^2 \hspace{5em}\stackrel{center}{(\underset{0}{h}~~,~~\underset{136}{k})}\qquad \stackrel{radius}{\underset{120}{r}} \\\\[-0.35em] ~\dotfill\\\\ ( ~~ x - 0 ~~ )^2 ~~ + ~~ ( ~~ y-136 ~~ )^2~~ = ~~120^2\implies x^2+(y-136)^2=14400`
