Core stretch A circular log has radius $1.3$ m. Its horizontal waterline is a chord of length \(2.

Question

Core stretch A circular log has radius $1.3$ m. Its horizontal waterline is a chord of length $2.0$ m below the centre. Find the vertical height of the log above the water. You may use the fact that the perpendicular from the centre of a circle to a chord bisects the chord. $O$ $2.0$ $1.3$

Accepted Answer

$1.3+\sqrt{0.69}\approx2.13$ m.
