The radio tower on a navy vessel continuously sends out signals in every direction to pick up any other vessels within a $11$11 km radius.
Let the tower be positioned at $\left(0,0\right)$(0,0) on the plane.
A submarine is $9.1$9.1 km East and $7.1$7.1 km North of the tower. What is its direct distance from the tower?
Give your answer to one decimal place.
Will the radio tower's signals pick up the submarine?
