a pottery manufacturer has an order to manufacture 5000 hanging vases to hold ½ pt. of water when full. The vases are designed so as to fit into the corner of a room. The faces of each vase are triangular in shape and intersect to form a pointed bottom. The area of the polygon cut out of the plane of the base by the lateral faces is 3sq.in. The height of the vase is 8 in. Compute the weight of pottery required if pottery weighs 130lb. per cu.ft.

Given that P is a point on the circle x^2 +y^2 - 4x +2y - 4=0. Find the longest distance from P to the y-axis.
Imagine a right circular cone with altitude H and slant height R. Let the radius of
the circular base be r. Imagine that the apex angle of the cone is "\\theta" . Now slit the
cone open by cutting along the slant height from the base to the apex. Unwrap the
slit cone to reveal a circular sector. Find the central angle of this sector, "\\alpha" , as a
function of "\\theta" .
