Construction workers are digging a tunnel through a mountain like the one below. The space inside the tunnels is going to be semicircular with a radius of 14 ft. (Note- there are TWO tunnels - one for eastbound traffic and one for westbound traffic. The building materials to create the tunnel will be semicircular on the inside but the "outside" will have the shape of a rectangular prism. The height of the structure is 45 ft. and the width of the entire structure is 72 ft. The tunnels are 711 ft. Tong. What is the volume of the material used to create the structure for the tunnels in cubic feet? Round your answer to the nearest cubic foot
