9 on its own can not be simplified. It needs to be a fraction.
Answer:
(x + [1/4])2 + (y - 1)2 = (97/16)
Step-by-step explanation:
(x + [1/4])2 + (y - 1)2 = (97/16)
this would be 94 hope it helps
Radius of curvature = 10'
Diameter of circle = 2 * 10' = 20'
height of segment = 2'
Let semi-chord be x.
Then by the intersecting chord property,
2*(20-2)=x^2
x^2=36
x=sqrt(36)=6
=>
chord=2x=2*6=12'
