Hey All,
I would appreciate some help with this question that is confusing me :)
_______________________________________________________________________

A floral clock in the shape of a circle is laid out in the city gardens. Assume the diameter of
the clock is 6 m and that its centre is at (3, 3) on an imaginary Cartesian grid where there is
1 m between coordinates. Find the equation of the straight line made by the minute hand
when the clock shows:
(a) 3.25 pm (b) 5.40 pm

The only thing I can work out at this stage is the equation of the actual circle which is:
(x-3)^2+(y-3)^2=9
