The parabolic arch of a bridge over a one-way road can be described by the equation y = -x^2 + 6, where x and y ar emeasured in
Vladimir [108]
So check the picture below

if we check the solutions or zeros for the equation, we get \bf y=-x^2+6\implies 0=-x^2+6\implies x=\pm \sqrt{6}

and as you can see in the picture, the value of "x" when y = 3.5, or the height of the truck is  \bf y=-x^2+6\implies 3.5=-x^2+6\implies x=\pm \sqrt{2.5}

the truck, ends up with a clearance of \bf \sqrt{2.5}-1.5 on either side, so, the maximum clearance, the truck can have, those two clearances added together, \bf 2(\sqrt{2.5}-1.5)

galina1969 [7]

Answer:

diameter of a circle = 12cm

Step-by-step explanation:

Area of a circle = πr²

113.04 cm² = πr²

First, search for radius (r) :-

r = √(113.04/π)

r = 6 cm

As diameter is equals to 2×radius

The diameter of a circle = 2 × 6cm

Final answer = 12 cm
