Standard form of circle (x-h)^2 + 9y-k)^2 = r ^2 where (h,k) is the center ....
the DIAMETER is 18 so the radius is 9 INCHES 9 INCHES = 3/4 ft r^2 = 9/16
now look at the answers that have this part 1st or 3rd one
(remember to keep everything in feet or in inches (feet is easier) )
The CENTER of the circle is now at (x,y) = (11, 5 2/3) because 5 ft 8 in = 5 2/3 ft (this was given in the Q)
this will be (h,k) which equation fits this (the first or third)????
This should get you started........
