You can find this using the a^2 + b^2 = c^2 method, substituting the length of the legs for a and b, while solving for c.

The Pythagorean theorem for finding the hypotenuse of a right triangle is a^2 + b^2 = c^2. So the equation goes as follows.
a^2 + b^2 = c^2
(3)^2 + (6)^2 = c^2
9 + 36 = c^2
45 = c^2
C = 6.708
