(a)The amount of water that the ice cream cup hold=the volume of ice cream cup(cylinder) Volume=pi*r^2*h=pi*(3)^2*8=72pi cm^3 ========================================== volume of cone=1/3*pi*r^2*h after solving r=2*sqrt3 cm Area of base cone=pi*r^2=2*pi*sqrt3 cm^2...

Hello, Can you help me in this question , In part a I must find the volume of cup(cylinder) In part b I must find radius but how can I find Area In part c ,d I don't know how can I solve it?? What is spanning angle and surface area?? Note : this question from previous exam but I...

Thank you very much for helping me..

Do you mean that you make comparison between standard sine curve and the graph .. because in my book they write phase shift =1/4*2pi=pi/2 but I don't know why they make this .. I attached the file that contain the question .. and if you can can tell me if mu solution to the...

I understand the concept of phase shift.. but in this graph how can I know the zero-phase position??

What is the meaning of phase and phase shift?? and How can I obtain phase shift from the sine curve ?? http://www12.0zz0.com/2009/01/16/17/965512159.jpg Note : I'm a begginer in physics , so please if you can , please explain the concept in details .. Thank you ..
