Answer: (x)^2 + (y)^2 = 90,000
Step-by-step explanation: we know that
The equation of the circle (the roof of the Colosseum) in standard form is equal to (x-h)^2 + (y-k)^2 =r^2
where
(h,k) is the center and r is the radius
we have
(h,k)=(0,0) ----> is the origin
----> the radius is half the diameter
substitute
