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 think this question is strange because In my course I study about (Sequences,functions,infinite series,matrices,vectors,equation of circle.
An ice cream shop offers 2 types of serving :cones and cylindrical cups . The ice cream cup is H=8cm in height , and D=6 cm in diameter...
(a) How much water the ice cream cup hold??
(b)if the ice cream cone height ,h=18 cm ,then what must be the area,A,and radius ,r,of the cone base ,for it to have the same volume as the cup??
(c)Find the general formula for the spanning angle Ф,of the sector made by the cone when it is split open on a flat surface .
(d)Find Surface Area S,of the ice cream cone with dimensions as in part (b)
if thickness,t=sqrt3/(5 pi) cm of the cone is made of edible matter such as sugar ...etc ,What is the volume of the matter that makes cone
