Charles and Olivia are trying to estimate the volume of water that could be held by the figure shown below, which is 10 feet high and has a circular top of a radius 20 feet. Charles proposes they approximate the volume by using a cylinder of radius 20 feet and height 10 feet. Olivia proposes that they instead use a circular cone connecting the top of the tank to the vertex at the bottom. Which solution is likely to be most accurate volume? 100 cubic feet 200 cubic feet 1,333 cubic feet 4,000 cubic feet

The vertices of rectangle ( P Q R S ) are graphed in the xy-plane with coordinates ( P(-3,-2), Q(-3,3), R(4,3) ), and ( S(4,-2) ). The rectangle ( P Q R S ) is reflected across the ( y )-axis and rotated ( 90^{circ} ) counterclockwise about the origin to form rectangle ( P^{prime} Q^{prime} R^{prime} S^{prime} ). What are the coordinates of point ( P^{prime} ) ? ( (-2,-3) ) ( (-2,3) ) ( (2,-3) ) ( (2,3) )
