This means that, using Pythagoras’ theorem, the equation of a circle with radius \(r\) and centre (0, 0) is given by the formula \(x^2+ y^2= r^2\). Find the equation of a circle with radius 3 ...
Look at triangles OAM and OBM. The hypotenuses (OA and OB) are the same, as they are both the radius of the circle ... and the radius is seven metres. Calculate the height of the tunnel.
