Question 1024148
A paper drinking cup is in the shape of a cone.  The angle at the bottom of the cone is 280and the slant height of the cone is 10 cm.Determine the maximum volume of water thatthis cup can hold.
-----------
280 must be the exterior angle --> 100 degs internal.
The sides are 50 degs from the axis of the cone.
---
Height = 10*cos(50) =~ 6.428 cm.
Radius = 10*sin(50) =~ 7.66 cm
{{{Vol = pi*r^2*h/3}}}
