A tunnel is 30 yards long and 15 yards wide. The height of the tunnel walls is 5 yards before the curve of the cylinder-shaped ceiling. What is the volume of the tunnel? Use 3.14 for pi. Round your answer to the nearest hundredth. By the way i don't know how to attatch the image that is to this question . its a image of a mailbox
The tunnel is made of two shapes and we can find the volume of each. Cuboid volume=15×5×30=2250 cu yds. Half cylinder volume=π(7.5)²30/2=843.75π=2649.38 cu yds. Total volume=4899.38 cu yds.
