I see this is a high school question.

So what equation have you been taught for SHM, the sine or the cosine equation?

If you are struggling to get the information given to fit your given equation, please check the extract below as I don't think you have quite copied it correctly.

 the amplitude at the center of the cone is A=1.5X10^-4m and t=0 and x=A (amplitude).
