In a model. It is shown that an arch of abridge is semi-elliptical with major axis horizontal if the length of the base is 9m and the heightest part of the bridge is 3m from the horizontal, then the best approximation of the height of the arch , 2m from the centre of the base is

` ( 11)/(4) m.`

` ( 8)/(3) m`

` (7)/(2) m `
